Question

The molecule having zero dipole moment is

Solution

Correct option is

 

A symmetrical molecules have zero dipole moment.

The dipole moment of  molecule is zero due to its symmetrical (triangular planar) structure.

The three fluorine atoms lie at the corners of an equilateral triangle with boron at the centre. Thus, the vectorial addition of the dipole moments of the three bonds gives a net sum of zero.
