Question

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

​

Answer 1

Answer:

→NH3 has higher dipole moment than NF3 .

» REASON:

● in case of NH3, nitrogen is more electronegative than hydrogen,so it tries to pull the electrons from hydrogen atoms.

● where as in case of NF3, fluorine being more electronegative than nitrogen tries to pull the electrons from nitrogen opposite from that of nitrogen.

hence due to this reason,

◎ NH3 HAS HIGHER DIPOLE MOMENT

Answer 2

Answer:In NH3, N is more electronegative than H. So, N pulls the electrons from H towards itself and so, the direction ofmoment due to the N-H bonds is in the same direction as that of the lone pair of electrons on Nitrogen. ... And, so wehave NH3 whose dipole moment is much higher than that of NF3.
