Answer & Solution
Correct Answer
(C) \(\mathrm{A}=\mathrm{Q} \quad \mathrm{B}=\mathrm{S} \quad \mathrm{C}=\mathrm{P} \quad \mathrm{D}=\mathrm{R}\)
Step-by-step Solution
Detailed explanation
A + HI (Heat): Strong reduction, removes all OH groups \(\rightarrow\) n-hexane \(CH_3-(CH_2)_4-CH_3\) \(\Rightarrow\) A = Q B + \(Br_2\) (aq): Mild oxidation, only oxidises aldehyde (\(-CHO\)) at \(C_1\) \(\rightarrow\) Gluconic acid \(HOOC-(CHOH)_4-CH_2OH\) \(\Rightarrow\) B =…
