9784193119 | Melting/Boiling Points: Ionic Compounds | Use Coulomb's law. Explanation: ions with smaller radii and/or larger charge will have greater electrostatic attraction and therefore have greater lattice energy, requiring more energy to melt/boil/dissolve. | 213 | |
9784205015 | Melting/Boiling Points: Molecules (covalent) | MUST MENTION IMFS see above. Example: H2O has a higher boiling point than CH4 because water has all three types of forces: LDF, dipole, and most importantly, hydrogen-bonding. CH4 only has LDF and thus the molecules are held together more weakly which requires less energy to boil/melt. etc. | 214 |
