Match the reactions in Column $(I)$ with the products formed in Column $(II)$.
Column $(I)$ Column $(II)$ $(A)$ Kolbe's reaction $(i)$ Salicylaldehyde $(B)$ Reimer-Tiemann reaction $(ii)$ Ethers $(C)$ Williamson synthesis $(iii)$ Ethanol $(D)$ Fermentation $(iv)$ Salicylic acid
| Column $(I)$ | Column $(II)$ |
| $(A)$ Kolbe's reaction | $(i)$ Salicylaldehyde |
| $(B)$ Reimer-Tiemann reaction | $(ii)$ Ethers |
| $(C)$ Williamson synthesis | $(iii)$ Ethanol |
| $(D)$ Fermentation | $(iv)$ Salicylic acid |
(A-IV, B-I, C-II, D-III) The correct matches are:
$(A)$ Kolbe's reaction produces Salicylic acid $(iv)$.
$(B)$ Reimer-Tiemann reaction produces Salicylaldehyde $(i)$.
$(C)$ Williamson synthesis is used for the preparation of Ethers $(ii)$.
$(D)$ Fermentation of sugars produces Ethanol $(iii)$.
Therefore,the correct sequence is $(A-iv, B-i, C-ii, D-iii)$.
