Answer & Solution
Correct Answer
(B) A - R B - P C - S D - Q
Step-by-step Solution
Detailed explanation
Reaction A: Warming benzene diazonium chloride with water yields phenol. Thus, A matches with R. Reaction B: Bromination of phenol in a non-polar solvent like \(CS_2\) at low temperature (\(273\) K) yields monobromophenols, primarily p-bromophenol as the major product. Thus, B…
