Question

An ester is boiled with KOH. The product is cooled and acidified with concentrated HCl. A white crystalline acid separates. The ester is (A) methyl acetate (B) ethyl acetate (C) ethyl formate (D) ethyl benzoate

Tardigrade Admin · Accepted Answer

Methyl acetate and ethyl acetate on hydrolysis gives CH3COOH which is a liquid. Similarly ethyl formate on hydrolysis will give formic acid which is also a liquid. Only ethyl benzoate on hydrolysis will give benzoic acid which is solid.
