Zero Dipole Moment Compounds | JEE Main PYQ
Number of compounds from the following with zero dipole moment is ______.

HF, H2, H2S, CO2, NH3, BF3, CH4, CHCl3, SiF4, H2O, BeF2

Correct Answer: 6

Explanation

H2, CO2, BF3, CH4, SiF4 and BeF2 are symmetric molecules, hence their individual bond dipoles cancel out resulting in zero net dipole moment.

All remaining molecules are either bent, pyramidal or unsymmetrical and hence polar.
