What is the characteristic physical state and odour of the mid-chain aliphatic carboxylic acids (spe — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Lower carboxylic acids (up to $C_3$) are colourless liquids with sharp, pungent odours. Mid-chain aliphatic carboxylic acids ($C_4$ to $C_9$) are colourless liquids characterized by a highly unpleasant, rotten butter smell. Higher members (> $C_9$) are wax-like, odourless solids due to low volatility.
