Correct answer: C

  1. Identify each item in List I

    • (A) Benzenesulphonyl chloride is the Hinsberg reagent.
    • (B) Hoffmann bromamide reaction converts an amide to an amine with one carbon less, and proceeds through isocyanate intermediate.
    • (C) Carbylamine reaction is the test for primary amines.
    • (D) Hoffmann orientation refers to elimination giving the less substituted alkene, i.e. Anti-Saytzeff product.

  2. Match with List II

    • (A)(A)(A) Benzenesulphonyl chloride →\to→ Hinsberg reagent →(III)\to (III)→(III)
    • (B)(B)(B) Hoffmann bromamide reaction →\to→ known reaction of isocyanates →(IV)\to (IV)→(IV)
    • (C)(C)(C) Carbylamine reaction →\to→ test for primary amines →(I)\to (I)→(I)
    • (D)(D)(D) Hoffmann orientation →\to→ Anti-Saytzeff →(II)\to (II)→(II)

  3. Final matching

    A−III,  B−IV,  C−I,  D−IIA-III,\; B-IV,\; C-I,\; D-IIA−III,B−IV,C−I,D−II

  4. Check options

    This corresponds to Option C.

  5. Comparison with stored answer

    Stored correct answer = C.

    Our derived answer also = C.
