Solution: (a) An ionic or electrovalent bond is shaped by the whole transference of a number of electrons from 1 atom to a different.

In NH3, the dipole times in the 3 N—H bonds are in the identical course given that the lone set of electron. But in NF3, the dipole moments with the a few N—F bonds are during the route reverse to that from the lone pair. Therefore, the resultant dipole second in NH3 is more than in NF3.
