Question
Write a note on solubility of carboxylic acids,
✓
Answer
→ Simple aliphatic carboxylic acids having upto four carbon atoms are miscible in water due to the formation of hydrogen bonds with water.
→ The solubility decreases with increasing number of carbon atoms. Higher carboxylic acids are practically insoluble in water due to the increased hydrophobic interaction of hydrocarbon part. Benzoic acid, the simplest aromatic carboxylic acid is nearly insoluble in cold water.
→ Carboxylic acids are also soluble in less polar organic solvents like benzene, ether, alcohol, chloroform, etc.
