Answer 1

Answer: (C)

(A) 2 molecules of benzaldehyde react with cyanide ions to form benzoin. This is a condensation reaction known as Benzoin condensation.
(B) In acidic medium, one molecule of phthalic anhydride condenses with 2 molecules of phenol to give one molecule of Phenolphthalein which is used as an acid-base indicator.
(C) When Phenyl benzoate is heated with anhydrous aluminium chloride, a mixture of ortho and para hydroxy benzophenone is obtained. This reaction is known as Fries rearrangement.
(D) Methyl salicylate is also known as oil of wintergreen.
