MCQ
Dipole moment is shown by
  • A
    $1, 4-$dichlorobenzene
  • B
    $cis$ $1, 2-$dichloroethene
  • C
    $trans$$1, 2-$dichloro$-2-$pentene
  • ✓
    $(b)$ and $(c)$
✓

Answer

Correct option: D.
$(b)$ and $(c)$
(d) cis isomer shows dipole moment while that of trans is zero or very low value. Trans $1, 2 $ di-chloro$-2-$pentene will also show dipole moment due to unsymmetry.
