2870716354constitutional isomerismcompounds with identical molecular formulas but differ in order in which the individual atoms are connected0
2870724114Isomers1
2870724115stereoisomerismisomers whose atoms are connected in the same order but differ in their spatial arrangement examples include (1) relatively stable and isolable cis-trans isomers (2) the rapidly equilibrating (and usually not isolable) conformational ones -cis/trans, anti/gauche, equatorial/axial, mirror-image stereoisomerism2
2870742522chirala molecule that is not superimposable on tis mirror image -molecules with one stereo center are always chiral -many chiral objects do not have stereo centers -only criterion for chirality is the non superimposable nature of object and mirror image3
2870746960enantiomereach isomer of the image-mirror image pair4
2870763228test for chiralitythe presence of absence of a plane of symmetry (mirror plane)-- one that bisects the molecule so that the part of the structure lying on one side of the plane mirrors the part on the other side chiral molecules cannot have a plan of symmetry5
2870770336optical activity of enantiomers-special interaction with light: optical activity -enantiomers are frequently called optical isomers -when plane-polarized light is passed through a sample of one of the enantiomers, the plan of polarization of the incoming light is rotated in one direction (either clockwise or counterclockwise)6
2870773068dextrorotatory-(dexter, Latin, right) -an enantiomer that rotates the plane of light in a clockwise sense as the viewer faces the light source -referred to as the (+) enantiomer7
2870774422levorotatory-laevus, Latin, left -counterclockwise rotation -(-) enantiomer8
2870777423ordinary light and plane-polarized light-bundles of electromagnetic waves that oscillate simultaneously in all planes perpendicular to the direction of the light beam -when such light is passed through a material called a polarizer, all but one of these light waves are "filtered" away, and the resulting beam oscillates in only one plane: plane-polarized light9
2870803664optical rotation-when light travels through a molecule, the electrons around the nuclei and in the various bonds interact with the electric field of the light beam. -If a beam of plane-polarized light is passed through a chiral substance, the electric field interacts differently with, say, the "left" and "right" halves of the molecule -this interaction results in a rotation of the plane of polarization is called optical rotation -the sample giving rise to it is referred to as optically active10
2870805895polarimeteroptical rotations are measured by using a polarimeter11
2870811074racemic mixture (racemate)a compound containing one stereo center is chiral and exists as a pair of enantiomers -A 1:1 mixture of enantiomers12
2870816599Absolute configuration: R-S sequence rules-there is no straightforward correlation between the sign of rotation and the structure of the particular enantiomer -x-ray diffraction can establish the absolute configuration13
2870831228stereocenters are labeled R or S-rank all four substituents in the order of decreasing priority -place the lowest-priority substituent farthest -if the progression from a to b to c is counterclockwise, the configuration at the stereocenter is named S (sinister, Latin, left) -if the progression is clockwise, the center is R (rectus, Latin, right) ex: (R)-2-bromobutane and (S)-2-bromobutanee the sign of the rotation of plane-polarized light maybe added if it is known, i.e. (S)-(+)-2-bromobutane and (R)-(-)-2-bromobutane14
2870858677sequence rules assign priorities to substituents(1) look at atoms directly attached to the stereocenter. Higher atomic number has higher priority. In regard to isotopes, the atom of higher atomic mass receives higher priority (2) look for the first point of difference (3) double and triple bonds are treated as if they were single, and the atoms in them are duplicated or triplicated at each end by the respective atoms at the other end of the multiple bond.15
2870878009Fischer projectionsimplified way of depicting tetrahedral carbon atoms and their substituents in two dimensions16
2870899416conversion of hawed-wedged line structures into fischer projections17
2870902935Fischer projections tell us the absolute configuration18
2870906416diastereomers-presence of more than one stereocenter stereoisomers that are not related to each other as object to mirror image. -Cis and trans isomers of cyclic compounds are examples of disastereomers -because they are not mirror images of each other, diastereomers are molecules with different physical and chemical properties -a compound with n stereocenters can have a maximum of 2^n stereoisomers19
2870971364meso compounda compound that contains two stereocenters but is superimposable with its mirror image (mess, Greek, middle) -the presence of an internal mirror plane20
2871091978In general, the formation of chiral compounds (e.g., 2-bromobutane) from chiral reactants (e.g., butane and bromine) yieldsracemates. Or, optically inactive starting materials furnish optically inactive products21
2871095756stereoselectivethe preference for the formation of one stereoisomer, when several are possible22
2871096027resolutionthe separation of enantiomers -It is achieved by the reaction of the racemate with the pure enantiomer of a chiral compound to yield separable diastereomers -chemical removal of the chiral reagent frees both enantiomers of the original racemate.23
2871098396chiral chromatographyanother way of separating enantiomers is by chiral chromatography on an optically active support -the sample is applied to the top of a column filled with an enantiopure chiral support. One enantiomer (green) interacts more strongly with the support than the other (red) and is relatively slow to pass through the column -the red enantiomer is eluted before its green mirror image. Commercial columns often use the glucose polymer cellulose as the chiral stationary phase.24

5023948166Thomas JeffersonHe was George Washington's first secretary of state. A Democrat-Republican, he was the nation's third president from 1801 to 1809. He stressed the basic principles of constitutional government and limited central government. He appeased the Federalists by maintaining the national bank and debt repayment plan of Hamilton, and carried on the neutrality policies of Washington and Adams. He reduced the size of the military, eliminated some federal jobs, repealed excise taxes, and lowered the national debt. In 1803, he made the Louisiana Purchase from France. (p. 131)0
5023948167Louisiana PurchaseIn 1803, President Thomas Jefferson purchased the Louisiana territory from France for $15 million. The purchase more that doubled the size of the United States, removed a European presence from the nation's borders, and extended the western frontier well beyond the Mississippi River. (p. 133)1
5023948188war hawksThe 1810 congressional election brought a group of young Democratic-Republicans to Congress. Led by Henry Clay and John C. Calhoun they gained influence in the House of Representatives. They argued that war with Britain was the only way to defend American honor, gain Canada, and destroy American Indian resistance on the frontier. (p. 139)2
5023948189Henry ClayIn 1810, he was a Kentucky member of the House of Representatives. He was a war hawk who argued for war with Britain. (p. 139)3
5023948190John C. CalhounIn 1810, he was a South Carolina member of the House of Representatives. He was a war hawk who argued for war with Britain. (p. 139)4
5023948185TecumsehThis Shawnee warrior, who along with his brother, attempted to unite all American Indian tribes east of the Mississippi River. (p. 138)5
5416983974ProphetThis Shawnee religious leader, who along with his brother, attempted to unite all American Indian tribes east of the Mississippi River. (p. 138)6
5023948186William Henry HarrisonIn 1811, this governor of the Indiana Territory, destroyed Shanee headquarters and put an end to Tecumseh's efforts to form an American Indian confederacy. (p. 138)7
5023948187Battle of TippecanoeAn 1811 battle, where U.S. troops led by William Henry Harrison did battle against American Indians led by Tecumseh. (p. 138)8
5023948170strict interpretation of ConstitutionPresident Thomas Jefferson was committed to a strict interpretation of the Constitution and rejected Alexander Hamilton's argument that certain powers were implied. When Jefferson made the Louisiana Purchase he was troubled because the Constitution did not state explicitly that a president could purchase foreign land. He finally argued that the president's powers to make treaties allowed for the purchase. (p. 133)9
5023948172John MarshallThis Federalist Chief Justice of the Supreme Court served in the position for 34 years. His decisions in landmark cases generally strengthened the federal government, often at the expense of states rights. (p. 134)10
5023948173judicial reviewIn 1803, Marbury v. Madison case, the Marshall court established the doctrine of judicial review by ruling that a law passed by Congress was unconstitutional. From this point on, the Supreme Court could overrule the legislative or executive branches if they believed a law was unconstituional. (p. 134)11
5026281821Marbury v. MadisonA Supreme Court case in 1803 where Chief Justice John Marshall ruled that a law passed by Congress was unconstitutional. This established the doctrine of judicial review, where the Supreme Court could overrule actions taken by the legislative and executive branches of the government. (p. 134)12
5023948175Aaron BurrHe was Thomas Jefferson's vice president from 1801 to 1804. A new vice president was chosen for Jefferson's second term. He then organised a failed conspiracy, attempting to unite New England states and secede from the United States. He killed Alexander Hamilton in a duel. In 1806 was tried for treason because of a plan to capture Mexico and possibly unite it with Louisiana. He was acquitted of the charge. (p. 135)13
5023948176QuidsIn 1812, they were "Old" Democratic-Republicans who criticized the War of 1812 because it violated the classic Democratic-Republican commitment to limited federal power and the maintenance of peace. (p. 140)14
5023948204Hartford Convention (1814)In December 1814, a special convention was held in Hartford, Connecticut. Bitterly opposed to the the War of 1812, some radical Federalist in the Northeast wanted to secede from the United States, but it was rejected. However, to limit the power of the Democratic-Republicans they adopted a proposal that a two-thirds vote of both houses would be required for any future declaration of war. (p. 141)15
5023948168Napoleon BonaparteIn the War of 1812 the United States based their hope for victory on Napoleon successfully fighting the British in Europe. However, in the spring of 1814, Napoleon's losses enabled the British to increase their forces in North America. (p. 141)16
5023948169Toussaint I'OuvertureHe led a rebellion against French rule on the island of Santo Domingo which resulted in heavy French losses. (p. 132)17
5023948177Barbary piratesThe United States had been paying the Barbary states on the North African coast in exchange for safe passage of U.S. ships in the Mediterranean. President Jefferson stopped paying the tribute, and the U.S. fought the Barbary Wars from 1801 to 1805. There was no decisive victory but it did offer some protection to U.S. ships in the region. (p. 136)18
5023948178neutralityAround 1804, the Napoleonic wars dominated Europe. Britain was seizing U.S. ships, confiscating the cargo and forcing sailors to join the British navy. This made it difficult for President Jefferson to maintain a position of not taking sides in the conflict. (p. 136)19
5023948179impressmentThe British practice of taking American sailors from American ships and forcing them to serve in the British navy. (p. 136)20
5023948180Chesapeake-Leopard affairIn 1807, the British warship Leopard attacked the American warship Chesapeake. Three U.S. sailors were killed and four were taken captive. Many Americans demanded war but Jefferson used diplomacy and economic pressure in response. (p. 136)21
5023948181Embargo Act (1807)In 1807, this act prohibited American trading ships from sailing to any foreign port. It was meant to force Britain and France to change their policies towards neutral vessels, by depriving them of American trade. The embargo backfired and brought greater economic hardship to the United States than Britain. In 1809 it was repealed. (p 136)22
5023948182James MadisonThe fourth President of the United States from 1809 to 1817. A Democrat-Republican and a close friend of Thomas Jefferson. A member of the Continental Congress and the Constitutional Convention, he strongly supported ratification of the Constitution. He was a contributor to The Federalist Papers. His presidency was marked by the War of 1812. (p. 137)23
5023948183Nonintercourse Act (1809)In 1809, this act provided that America could now trade with all nations except Britain and France. (p. 137)24
5023948184Macon's Bill No. 2 (1810)When economic hardships continued into 1810, Nathaniel Macon, a member of Congress, introduced a bill that restored U.S. trade with both Britain & France. It also provided that if either France or Britain formally agreed to respect neutral rights at sea, then the U.S. would prohibit trade with the foe of that nation. (p. 138)25
5023948191War of 1812A war between the United States and Great Britain caused by American outrage over the impressment of American sailors by the British and British aid to the Indians attacking the Americans on the western frontier. The War Hawks (young westerners led by Henry Clay and John C. Calhoun) argued for war in Congress. American troops attempted an invasion of Canada, but it was repulsed by British defenders. Numerous naval battles occurred and at one point the British marched through Washington, D.C. and burned the White House. In December 1814 the Treaty of Ghent was reached and territory was returned to the pre-war status. Two weeks later, Andrew Jackson's troops defeated the British at the Battle of New Orleans, not knowing that a peace treaty had already been signed. (p. 138)26
5023948192Old IronsidesThe nickname for the U.S. warship, Constitution. In 1812, it raised American morale by sinking a British ship off the coast of Nova Scotia. (p. 140)27
5023948193Battle of Lake ErieProbably the most important U.S. naval victory in the War of 1812. Captain Oliver Hazard Perry led the U.S. to victory against the British. (p. 140)28
5023948194Oliver Hazard PerryThis naval captain won the Battle of Lake Erie in the War of 1812. His famous quote was, "We have met the enemy, and they are ours." (p. 140)29
5023948195Battle of the Thames RiverThis naval battle, near Detroit, was led by General William Henry Harrison. The U.S. defeated the British, and the American Indian Tecumseh was killed. (p. 140)30
5023948196Thomas MacdonoughIn 1814, this U.S. naval commander defeated a British fleet on Lake Champlain. As a result the British had to retreat and abandon their plan to invade New York and New England. (p. 140)31
5023948197Battle of Lake ChamplainA battle where the British fleet was defeated and was forced to retreat and to abandon their plans to invade New York and New England. (p. 140)32
5023948199Andrew JacksonIn the War of 1812 this U.S. general defeated the Creek nation at the Battle of Horseshoe Bend. The British were trying to control the Mississippi River and he defeated them at the Battle of New Orleans. He would later become the seventh president of the United States. (p. 141)33
5023948200Battle of Horseshoe BendIn March 1814, General Andrew Jackson defeated the Creek nation, an important British ally. The battle was fought in present-day Alabama and ended American Indian resistance in that area. (p. 141)34
5023948201Creek NationThis American Indian tribe was an important British ally in the War of 1812 until being defeated by Andrew Jackson. (p. 141)35
5023948202Battle of New OrleansOn January 8, 1815, General Andrew Jackson led U.S. troops that defeated the British at New Orleans. At that time communications were much slower and the armies did not know that the Treaty of Ghent had ended the war two weeks earlier. (p. 141)36
5023948203Treaty of Ghent (1814)The peace treaty that ended the War of 1812. The terms halted fighting, returned all conquered territory to the prewar claimant, and recognized the pre war boundary between Canada and the United States. (p. 141)37
5023948171Lewis and Clark ExpeditionIn 1804, Captain Meriwether Lewis and Lieutenant William Clark left St. Louis, Missouri on an expedition to the Pacific coast. They travelled up the Missouri River to the Great Divide, and then down the Columbia River to the Pacific Ocean. the expedition provided greater scientific knowledge of the region, stronger claims to the Oregon Territory, better relationships with the American Indians, and more accurate maps. (p. 134)38
5023948198Francis Scott KeyHe wrote our national anthem while observing the British attack on Fort McHenry in Baltimore. (p. 141)39
