Question

Which one of the following molecules, has zero dipole moment? (A)  BF3  (B)  NH3  (C)  CH2Cl2  (D)  SO3

Tardigrade Admin · Accepted Answer

BF3 has zero dipole-moment as it is a planar molecule with F?B?F bond angle 120° . Hence, bond moments cancel each other. The resultant dipole moment becomes zero.

Q. Which one of the following molecules, has zero dipole moment?

$B F_{3}$

$N H_{3}$

$C H_{2} C l_{2}$

$S O_{3}$

$B F_{3}$ has zero dipole-moment as it is a planar molecule with F?B?F bond angle $120^{\circ}$ . Hence, bond moments cancel each other. The resultant dipole moment becomes zero.
