Show answer and solution
Correct option: A
Solution
Hoffmann Degradation of amides uses Br₂/NaOH (III). Clemmensen reduction of carbonyl compounds uses Zn-Hg/HCl (IV). Cannizzaro reaction (disproportionation of aldehydes without α-H) uses Conc. KOH/Δ (I). Reimer-Tiemann reaction (formylation of phenol) uses CHCl₃ and NaOH followed by H₃O⁺ (II). This gives A→III, B→IV, C→I, D→II.
