  • A
    $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CONH}_{2}$
  • B

  • C
    $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OCH}=\mathrm{CH}_{2}$
  • ✓
    $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}=\mathrm{CHCH}_{2} \mathrm{NH}_{2}$
✓

Answer

Correct option: D.
$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}=\mathrm{CHCH}_{2} \mathrm{NH}_{2}$
d
$\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{2}-\mathrm{NH}_{2}$

This is non conjugated compound.
