Question

Dipole moment of $NH_3$ is greater than that of $NF_3$ . Nitrogen is more electronegative than fluorine.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Answer

If assertion is true but reason is false

Explanation

Solution

In case of $NH_3$ , the orbital dipole due to lone pair is in the same direction as the resultant dipole moment of the three $N - H$ bonds whereas in $NF_3$ the orbital dipole is in the direction opposite to the resultant dipole moment of three $N?
