Match Amino Acids with Tests for Functional Groups in Side Chains

To determine the correct matching between the amino acids in List-I and the functional group tests for their side chains in List-II, we analyze the side chain structure of each amino acid:

1. A. Glutamine:

   • Side chain: $-\text{CH}_2\text{CH}_2\text{CONH}_2$
   • Functional Group: Primary Amide ($-\text{CONH}_2$)
   • Specific Test: Primary amides undergo Hoffmann bromamide degradation (IV) when treated with $\text{Br}_2$ and $\text{KOH}$.
   • Match: $\text{A} \rightarrow \text{IV}$

2. B. Lysine:

   • Side chain: $-\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{NH}_2$
   • Functional Group: Primary Amine ($-\text{NH}_2$)
   • Specific Test: Primary amines react with benzenesulfonyl chloride in Hinsberg's test (I) to form a sulfonamide soluble in alkali.
   • Match: $\text{B} \rightarrow \text{I}$

3. C. Tyrosine:

   • Side chain: $-\text{CH}_2-\text{C}_6\text{H}_4-\text{OH}$ (para-substituted phenol)
   • Functional Group: Phenolic Hydroxyl group ($-\text{OH}$)
   • Specific Test: Phenols give a characteristic violet/colored complex with Neutral } \text{FeCl}_3\text{ test (II).
   • Match: $\text{C} \rightarrow \text{II}$

4. D. Serine:

   • Side chain: $-\text{CH}_2\text{OH}$
   • Functional Group: Aliphatic Alcoholic Hydroxyl group ($-\text{OH}$)
   • Specific Test: Alcoholic $-\text{OH}$ groups yield a red color solution with the Ceric ammonium nitrate test (III).
   • Match: $\text{D} \rightarrow \text{III}$

Combining these matches, we get: $\text{A-IV, B-I, C-II, D-III}$

This corresponds to Option B.
