Q. Match the compounds given in List-I with List-II and select the suitable option using the code given below. [table] List-I | List-II ; a. Benzaldehyde | (i) Phenolphthalein ; b. Phthalic anhydride | (ii) Benzoin condensation ; c. Phenyl benzoate | (iii) Oil of wintergreen ; d. Methyl salicylate | (iv) Fries rearrangement [/table]
A) a(ii), b(iii), c(iv), d(i)
B) a(ii), b(i), c(iv), d(iii)
C) a(iv), b(i), c(iii), d(ii)
D) a(iv), b(ii), c(iii), d(i)
Explanation
[Solution from source] Benzaldehyde undergoes benzoin condensation; phthalic anhydride condenses with phenol to give phenolphthalein; phenyl benzoate undergoes Fries rearrangement to hydroxybenzophenones; methyl salicylate is oil of wintergreen. Only one code gives all four pairs correctly. Answer (2).
