Edexcel IAL Chemistry A2 15.10 Hydrogen bonding in carboxylic acids
Use the -COOH group explicitly: show how it donates and accepts hydrogen bonds, then compare the resulting forces with esters, aldehydes or hydrocarbons.
How this is tested
- Draw a water molecule hydrogen-bonded to a carboxylic acid with lone pairs and dipoles.
- Compare boiling temperatures using carboxylic acid hydrogen bonding between molecules.
- Compare water solubility by counting possible hydrogen bonds with water.
