Chemistry Question from JEE Main 2023 · 10 April, Shift 1

Isomeric amines with molecular formula C8H11N\mathrm{C_8H_{11}N} give the following tests:

(P) Can be prepared by Gabriel phthalimide synthesis. (Q) Reacts with Hinsberg’s reagent to give a solid insoluble in NaOH\mathrm{NaOH}. (R) Reacts with HONO\mathrm{HONO} followed by β\beta-naphthol in NaOH\mathrm{NaOH} to give a red dye.

Isomer (P), (Q), and (R), respectively, are:

  • A
    Three amine structures are shown as option 1, including benzyl-substituted and aromatic amine isomers with different amine classes.
  • B
    Three amine structures are shown as option 2, containing one primary aliphatic amine, one secondary amine, and one aromatic primary amine isomer.
  • C
    Three amine structures are shown as option 3, including aromatic and aliphatic amine isomers with varying substitution patterns and amine classes.
  • D
    Three amine structures are shown as option 4, consisting of one primary amine, one tertiary amine, and one aromatic primary amine isomer.
