the correct answer will be marked as brainiliest and get a follow! ​

Answer 1

Answer:

Step-by-step explanation:If you consider all of them in para position, Cl-Ph-Cl, Br-Ph-Br and CN-Ph-CN will have net zero dipole moment (since all of these are linear functional groups). If they are not in para position, NONE of the mentioned compounds will have zero dipole moment.

Answer 2

Answer:

option a )  1,4 - dichlorocyclohexane    is the correct answer.

The other three compounds have zero dipole moment.
