Answer & Solution

Correct Answer

(C) \(\mathrm{A}=\mathrm{Q} \quad \mathrm{B}=\mathrm{R} \quad \mathrm{C}=\mathrm{S} \quad \mathrm{D}=\mathrm{P}\)

Step-by-step Solution

Detailed explanation

Reaction A: Benzenediazonium chloride reacts with (i) \(H_2O\) to form phenol. Then, (ii) \(CHCl_3 + NaOH(aq)\) followed by (iii) \(dil. HCl\) performs the Reimer-Tiemann reaction on phenol, yielding salicylaldehyde (o-hydroxybenzaldehyde). This matches product Q. Reaction B:…
