Question

State True or False.

Statement: Dipole moment of $N{F}_3$ is less than that of $N{H}_3$

• A. True
• B. False

Answer 1

The correct option is A True

The dipole moment of $N{H}_3$ is higher in comparison to $N{F}_3$.
In case of $N{H}_3$, the dipole vectors of $N-H$ bonds and $N-$ lone pair are in the same direction and they reinforce each other.
In case of $N{F}_3$, the dipole vectors of $N-F$ bonds and $N-$ lone pair are in the opposite direction and they cancel each other.

The given statement is True.
