Consider the given chemical reaction :

Product " A " is :

(A)picric acid
(B)oxalic acid
(C)acetic acid
(D)adipic acid✓ Correct

Answer: (D)

Solution

Hot acidic

K M n O_{4}

oxidatively cleaves a ring carbon–carbon double bond, opening a cyclic alkene into a straight-chain dicarboxylic acid. For a six-membered cyclic alkene (cyclohexene) this cleavage gives

cyclohexene [O] H O O C - (C H_{2})_{4} - C O O H

which is adipic acid (hexanedioic acid) — the only symmetric

C_{6}

diacid among the options, matching product A.
