Statement-I: Dipole moment of ${\mathrm{NF}}_3$is less than that of ${\mathrm{NH}}_3$ 

Statement-2: Polarity of $\mathrm{N}-\mathrm{F}$ bond is less than that of $\mathrm{N}-\mathrm{H}$ bond

Choose the correct option:

Dipole moment vectors are in compensatory mode.

Dipole moment vectors are additive in nature.

Each $\mathrm{N}-\mathrm{H}$ bond in ${\mathrm{NH}}_3$ has a dipole moment that is directed toward nitrogen because H is less electronegative than nitrogen. The dipole moment of the resulting molecule, which has a tetrahedrally structured molecule with three $\mathrm{N}-\mathrm{H}$ bonds, points in the same direction as the dipole produced by the nitrogen lone pair. However, because F is more electronegative than N in ${\mathrm{NF}}_3$, the outcome is different from that of a lone pair dipole. decreasing the net dipole as a result.
