• A. A-4, B-1, C-3, D-2
• B. A-4, B-2, C-3, D-1
• C. A-2, B-3, C-4, D-1
• D. A-2, B-1, C-4, D-3

Answer 1

Answer: (D)

A-2, B-1, C-4, D-3

(A) Benzaldehyde $\to$ Benzoin condensation (2)

The benzoin condensation is a reaction between two aldehydes, particularly benzaldehyde.

(B) Phthalic anhydride $\to$ Phenolphthalein (1)

Phenolphthalein is synthesized by electrophilic aromatic substitution of phthalic anhydride and 2 equivalents of phenol in the presence of concentrated methanesulfonic acid at 90 $℃$.

(C) Phenyl benzoate $\to$ Fries rearrangement (4)

The Fries rearrangement of phenyl benzoate yields ortho- and para‑hydroxybenzophenone

(D) Methyl salicylate $\to$ Oil of wintergreen (3)

Methyl salicylate known as oil of wintergreen is an organic compound with the formula $C_6{H}_4\left(OH\right)\left(C{O}_{2}C{H}_3\right)$. It is the methyl ester of salicylic acid.
