Answer 2

The least polar among the following is:

(c) CH4

- The resultant dipole moment of NH3 is 1.47 D.

- The resultant dipole moment of NF3 is 0.23 D.

- The resultant dipole moment of CH4 is 0 D which is the lowest among the given options.

- Hence, CH4 is the least polar.

- The resultant dipole moment of HCl is 1.07 D.
