The Answer is ( C )
B will Not have a non zero dipole moment ...
The molecules that will have dipole moment are:
(a)2,2-dimethylpropane
(b)trans-2-pentene
(c)cis-3-hexene
(d)2,2,3,3-tetramethylbutane
TRANS compounds have A resultant Dipole Moment and not Cis compounds
thus (b)
but HERE the cis compound will also have a dipole moment thus (c) is the second answer
(B),(C) are the correct answer
it is more than one correct
The Answer is ( C )
B will Not have a non zero dipole moment ...
sorry everyone.....i stupidly thought about "cyclohexene" !!!!! ssooorrrryyyy for the trouble !!!
