Chemical Bonding And Molecular Structure Question 16

Question 16 - 2024 (30 Jan Shift 2)

Given below are two statements:

Since fluorine is more electronegative than nitrogen, the net dipole moment of $NF_3$ is less than $NH_3$.

In $NH_3$, the orbital dipole due to lone pair and the dipole moment of $N-H$ bonds are in opposite direction, but in $NF_3$ the orbital dipole due to lone pair and dipole moments of $N-F$ bonds are in same direction.

In light of the above statements, choose the most appropriate option from those given below.

(1) Statement I is true but Statement II is false.

(2) Both Statement I and Statement II are false.

(3) Both statement I and Statement II are true.

(4) Statement I is false but Statement II is true.
