Answer:
1. Lower aliphatic carboxylic acids containing upto four carbons are miscible with water due to formation of
intermolecular hydrogen bonds between carboxylic acid molecules and solvent water molecules.
2. The solubility of carboxylic acids in water decreases with increase in molecular mass.
3. Higher carboxylic acids are practically insoluble in water due to the increased hydrophobic (water hating) interaction of hydrocarbon part with water.
4. Aromatic acids like benzoic acid are also practically insoluble in water at room temperature.
5. Water insoluble carboxylic acids are soluble in less polar organic solvents like ether, alcohol, benzene, etc.
