Potassium benzoate; Benzoic acid

Vedclass · Answer

(B) The oxidation of alkyl benzene side chains with $KMnO_4/KOH$ (alkaline potassium permanganate) results in the cleavage of the side chain to form the potassium salt of benzoic acid (potassium benzoate, $P$).This reaction is a standard method for the oxidation of alkyl groups attached to a benzene ring.Upon subsequent acidification with $H_3O^+$, the potassium benzoate $(P)$ is converted into benzoic acid $(Q)$.Therefore, $P$ is potassium benzoate and $Q$ is benzoic acid.

Identify $P$ and $Q$ in the above reaction respectively.
