Question

The dipole moment of
is 1.5 D. Then dipole moment of this compound will be:

• A. 0 D
• B. 1.5 D
• C. 2.86 D
• D. 2.25 D

Answer 1

The correct option is B 1.5 D



Dipole moment of Cl at ${120}^{\circ }$ will have resultant dipole moment at ${180}^{\circ }$. Thus, it will get cancel with other Cl at ${180}^{\circ }$. Hence, the dipole moment is
$\mu =1.5D$
