JEE Main 2025 — 28 January, Morning Shift — Question 39

The products A and B in the following reactions, respectively are

A⟷Ag−NO2CH3−CH2−CH2−Br→AgCNB\mathrm{A} \stackrel{\mathrm{Ag}-\mathrm{NO}_{2}}{\longleftrightarrow} \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{Br} \xrightarrow{\mathrm{AgCN}} \mathrm{B}

  1. Option A:

    CH3−CH2−CH2−ONO,CH3−CH2−CH2−NC\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{ONO}, \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{NC}

  2. Option B:

    CH3−CH2−CH2−ONO,CH3−CH2−CH2−CN\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{ONO}, \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CN}

  3. Option C:

    CH3−CH2−CH2−NO2,CH3−CH2−CH2−CN\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{NO}_{2}, \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CN}

  4. Option D:

    CH3−CH2−CH2−NO2,CH3−CH2−CH2−NC\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{NO}_{2}, \mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{NC}
