The molecule (s) that will have dipole moment is/are:

Options

A. `2,2` Dimethyl propane
B. trans-`2`-Pentene
C. cis -`3`- Hexene
D. `2,2,3,3`-Tetramethyl butane

Answer

B, C

Explanation

a.
All vector cancel each other, so `mu=0`
b.
Vectors due to `Me` and ethyl do not cancel each other, so have net vector. Thus `mu gt 0`
c.
Two vector do not cancel and give net resultant vector. So `mu gt 0`.
d.
All vector cancel each other so `mu = 0`.
