Question

The dipole moment of chlorobenzene 

 

 is 1.5 D. The dipole moment of

 

(a) 2.86D 

(b) 2.25D 

(c) 1.5D 

(d) 0D

Answer 1

Correct option: (c) 1.5D

Explanation:

Dipole moments of 2Cl and 5Cl Dipole moments of 2Cl and 5Cl

It is due 1 Cl and 3 Cl μ2

= (1.5)2 + (1.5)2 + 2 x 1.5 x 1.5 cos 120 

∴  μ = 1.5 D
