Question

Match the compounds given in List-I with List-II and select the suitable option from the code given below:

**List-I**
(A) Benzaldehyde
(B) Phthalic anhydride
(C) Phenyl benzoate
(D) Methyl salicylate

**List-II**
(i) Phenolphthalein
(ii) Benzoin condensation
(iii) Oil of wintergreen
(iv) Fries rearrangement

Accepted Answer

1. **Benzaldehyde (A):** Undergoes **Benzoin condensation** when heated with ethanolic potassium cyanide (KCN) to form benzoin. Matches with **(ii)**.
2. **Phthalic anhydride (B):** Condenses with phenol in the presence of concentrated sulphuric acid to form **Phenolphthalein**, a common acid-base indicator. Matches with **(i)**.
3. **Phenyl benzoate (C):** Undergoes **Fries rearrangement** in the presence of anhydrous aluminum chloride ($AlCl_3$) to form ortho- and para-hydroxybenzophenones. Matches with **(iv)**.
4. **Methyl salicylate (D):** Is an ester commonly known as **Oil of wintergreen**, used in perfumery and medicine. Matches with **(iii)**.

Therefore, the correct sequence is (A)-(ii), (B)-(i), (C)-(iv), (D)-(iii).
