| Question | Answer |
| Carboxylic Acid General Formula | CnH2nO2 |
| Benzoic Acid | Acid group attached to benzene ring |
| Physical properties | # High BP for relative mass |
| As length of Carbon chain increases | BPT increases - the bigger the molecule the more VDW |
| Boiling Point increases with straight molecules | # Greater branching # Lower intermolecular VDW forces # Low BPT |
| Solubility | # H bonds form between H2O molecules and individual molecules of acid |
| Solubility decreases with size | # Longer hydrocarbon tails get between water molecules and break H bonds |
