Question

Which one has zero dipole moment among NH3, SnCl2,PH3, CCl4

Answer 1

Answer:

CCl4

Explanation:

CCl4 is a non polar molecule.

This is due to the cancellation of all the dipoles of this molecule due to its symmetry,Actually,all the C-Cl bonds are polar but molecule is non polar over all.

Among these molecules,CCl4 is non polar

Answer 2

Explanation:

CCl4 have zero dipole.
