Regarding the aqueous solubility of carboxylic acids, which of the following statements are chemical — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Lower aliphatic acids ($C_1$ - $C_4$) are completely water-soluble because the hydrophilic $-COOH$ group effectively forms H-bonds with $H_2O$. However, as the non-polar, hydrophobic hydrocarbon chain/ring increases in size, it repels water, causing higher acids and aromatic acids (like Benzoic acid) to become increasingly insoluble.
