. Dipole moment of NH3 is more/less than NF3

A: more

B: less

Best Answer

Explanation:

NH₃ has more dipole moment than NF₃.
In NH₃,N is more electronegative than H. So,N pulls the electrons from H towards itself.

So, the direction of the moment due to the N-H bonds is in the same direction as that of the lone pair of electrons on Nitrogen.

Final answer:

The correct option is A: more
