Solution

(A) Benzoin condensation When an ethanolic solution of benzaldehyde is heated with strong alkali like $\mathrm{KCN}$ or $\mathrm{NaCN}$, we get benzoin.
(B) Formation of phenolphthalein When phenol is reated with phthalic anhydride in the presence of concentrated $\mathrm{H}_2 \mathrm{SO}_4$, it gives phenolphthalein, an indicator.
(C) Fries rearrangement Phenyl benzoate when heated with anhydrous $\mathrm{AlCl}_3$ in the presence of inert solvent gives ortho-and para-hydroxybenzophenone. In this rearrangement, there is a benzoyl group migration from the phenolic oxygen to an ortho-and para-position.
(D) Methylsalicylate
(A chief constituent of oil of wintergreen)
