MCQ
The molecules having dipole moment are $ ...........$
  • A
    $2, 2-$ Dimethylpropane.
  • ✓
    Trans $-$ Pent $-2-$ ene.
  • C
    Cis $-$ Hex $-3-$ ene.
  • D
    $2, 2, 3, 3 -$ Tetramethylbutane.
✓

Answer

Correct option: B.
Trans $-$ Pent $-2-$ ene.
Trans $-$ pent $-2-$ ene shows net dipole moment because of different groups attached and cis $-$ Hex $-3-$ ene shows dipole moment because of $\mathrm{C}_2 \mathrm{H}_5$ groups are inclined to each other at an angle of $60^\circ$ so, has resultant dipole moment.
