Step-by-step solution

(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. H ₂ SO ₄ , it gives phenolphthalein, an indicator. (c) Fries rearrangement Phenyl benzoate heated with anhydrous 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-pos
