Question

Match List–I with List–II.}

Choose the correct answer.

• A. A–IV, B–II, C–I, D–III
• B. A–IV, B–II, C–III, D–I
• C. A–II, B–IV, C–I, D–III
• D. A–II, B–IV, C–III, D–I

Answer 1

The Correct Option is D

Concept: Different functional groups respond differently to specific qualitative reagents.
Step 1:A. Diethyl amine vs Ethyl amine} Ethyl amine is a primary amine and gives the carbylamine test. \[ CHCl_3 + KOH,\ \Delta \] Thus \[ A \rightarrow II \]
Step 2:B. Acetaldehyde vs Acetone} Acetaldehyde gives Tollens' test but acetone does not. Reagent: \[ \text{Ammoniacal silver nitrate} \] Thus \[ B \rightarrow IV \]
Step 3:C. Ethanol vs Phenol} Phenol gives a violet complex with neutral \(FeCl_3\). Thus \[ C \rightarrow III \]
Step 4:D. Benzoic acid vs Cinnamic acid} Cinnamic acid has a C=C double bond which decolorizes bromine water. Thus \[ D \rightarrow I \] Hence the correct match is: \[ A-II,\ B-IV,\ C-III,\ D-I \] \[ \boxed{A-II,\ B-IV,\ C-III,\ D-I} \]
