The correct answer is:
$2 \quad 1 \quad 4 \quad 3$
(a) Benzoin condensation : Heating ethanolic solution with strong alkali like KCN or NaCN, benzoin is obtained.
(b) Formation of phenolphthalein phenol is treated with phthalic anhydride in the presence of conc. $\mathrm{H}_{2} \mathrm{SO}_{4}$, it gives phenolphthalein, an indicator.
(c) Fries rearrangement Phenyl benzoate heated with anhydrous $\mathrm{AlCI}_{3}$ in the presence of inert solvent gives ortho-and Para-hydroxybenzophen one. In this rearrangement, there is only a benzoyl group migration from the phenolic oxygen to an ortho-and para-position.
(d) Methylsalicylate
(A chief constituent of oil of wintergreen)
