Answer:
Correct Answer: 43. $(a, c, d)$
Solution:
- PLAN This problem can be solved by using concept of conformational analysis of given organic compound. To solve the question draw the stable conformational structures of organic compound and determine the net resultant dipole moment.
The conformations of the given compound are as follows
(Me-Me)gauche
(Br-Me)gauche
(Cl-Me)gauche
These three have non-zero dipole moment due to non-cancellation of all dipole moment created by $C-Cl$ and $C-Br$ bond.
