Question Explanation:

Match the reactions in List-I with their correct reagents in List-II.

Concept:

This question is based on Hofmann degradation, Clemmensen reduction, Cannizzaro reaction and Reimer-Tiemann reaction.

Solution:

1. Hofmann degradation uses Br₂/NaOH $\to$ (A)–III.

2. Clemmensen reduction uses Zn–Hg/HCl $\to$ (B)–IV.

3. Cannizzaro reaction requires Conc. KOH/ $Δ$ $\to$ (C)–I.

4. Reimer–Tiemann reaction uses CHCl₃ + NaOH/H₃O⁺ $\to$ (D)–II.

Final Answer: Option (C)

List - I Reaction	List - II Reagents
(A) Hoffmann Degradation	(I) Conc. KOH, $Δ$
(B) Clemenson reduction	(II) $CHCl_{3}, NaOH / H_{3} O^{+}$
(C) Cannizaro reaction	(III) $Br_{2}, NaOH$
(D) Reimer-Tiemann reaction	(IV) $Zn - Hg / HCl$
