What You Should Learn From This Chapter:
1. Be able to recognize isomers and what type they are.
2. Know the seven functional groups and what properties they give to molecules.
5165900061 | Carbon's Versatility | Forms 4 covalent bonds that lead to a tetrahedral shape. Also, it can bond easily with itself. | 0 | |
5165900062 | Structural Isomers | Different in covalent arrangements of their atoms. | ![]() | 1 |
5165900063 | Cis-Trans Isomers | Same covalent partnership but different in spatial arrangements. They arise from the inflexibility of double bonds. | ![]() | 2 |
5165900064 | Enantiomer Isomer | Molecules that are mirror images of each other. Usually involve an asymmetric carbon. | ![]() | 3 |
5165900065 | Importance of Variations | Organisms are sensitive to even the most subtle variations in molecular architecture. | 4 | |
5165900066 | Functional Groups | A group of atoms attached to a carbon skeleton that have consistent properties. Their number and kind give properties to the molecule. | ![]() | 5 |
5165900067 | Hydroxyl Groups | A hydrogen atom bonded to an oxygen atom that is very polar, allowing the material to be hydrophillic. They form alcohols. (-OH) | ![]() | 6 |
5165900068 | Carbonyl Group | A carbon atom joined to an oxygen atom by a double bond. Aldehydes and Ketones are the two types of compounds in this group. (-C=O) | ![]() | 7 |
5165900069 | Aldehyde | A carbonyl group at the end of a carbon skeleton. Sometimes written as (-CHO). Looks like: -C=O | H | ![]() | 8 |
5165900070 | Ketones | A carbonyl group in the middle of a carbon chain. -C-C-C- || O | ![]() | 9 |
5165900071 | Carboxyl Groups | Group with a carbon double bonded to an oxygen and a hydroxyl group. They are acidic and make up Carboxylic Acid. Sometimes written as (-COOH) -C=O | O-H | ![]() | 10 |
5165900072 | Carboxylic Acids | Donate H+ (Acid) and form many weak organic acids. | ![]() | 11 |
5165900073 | Amino Group | Nitrogen Bonded to two hydrogens. They form compound called amines and act as bases. -N-H | H | ![]() | 12 |
5165900074 | Sulfhydryl Group | Sulfur bonded to a hydrogen. This forms compounds called thiols that help with protein structure. (-SH) | ![]() | 13 |
5165900075 | Phosphate Group | Phosphorous with four oxygen atoms that causes a net -2 charge. Sometimes written as "Pi", and involved with energy transfers. Also is acidic. (-PO4) | ![]() | 14 |
5165900076 | Methyl Group | Carbon bonded to three hydrogens. It is very non polar and therefore hydrophobic. (-CH3) | ![]() | 15 |
