If the dipole moment of the following molecule is 1.5D

Then the dipole moment of the following compound will be

Options

A. 1.5 D
B. 2.25 D
C. 1D
D. 3 D

Answer

A

Explanation

, the bond moment at para positions cancel due to opposite direction. The other two groups are meta to each other, thus angle between the two bond moments is `120^(@)` and hence, `mu =1.5 D`
