Question: The dipole moment of ![](https://cdn.pureessence.tech/canvas_505.png?top_left_x=918&top_left_y=1517&...

The dipole moment of is 1.5 D. The dipole moment of is:

A

1 D

B

1.5 D

C

2.25 D

D

3 D

Answer

1.5 D

Explanation

Solution

Resultant dipole moment of C – X dipoles in 1, 4 position is zero. The resultant of other two C – X dipoles in 3,5- position

= (1.5)2+(1.5)2+2×1.52×cos⁡120º\sqrt{(1.5)^{2} + (1.5)^{2} + 2 \times 1.5^{2} \times \cos 120º}= 1.5 D
