Q. The molecules that have non-zero dipole moment, are
(1) trans-$2$-butene
(2) trans-$2$-pentene
(3) $2,2,3,3$-tetramethyl butane
(4) cis-$3$-hexene

BHUBHU 2009

Solution:

Dipole moment is zero for symmetrical molecule. Tran $5-2$-pentene and cis-$3$-hexene, being unsymmetric, have some dipole moment.
