Question

Which out of NH₃ and NF₃ has higher dipole moment and why?

Answer 1

hope u will understand

Answer 2

1.  NH3, N has more electronegativity than H, so the charge is directed from hydrogen to nitrogen.

This implies that  resultant dipole moment add up in a same direction.

2.  NF3, F has more electronegativity than N, so the charges move in direction from nitrogen to fluorine.

This implies that resultant dipole moment being in opposite directions cancel out each others effect.

Therefore, NH3 has more dipole moment than NF3.
