`NH_3` and `NF_3`, both the molecules have pyramidal shape with a lone pair of electrons on nitrogen atom. Why does the dipole moment of `NH_3` is greater than that of `NF_3`?
Choose the correct option.

Options

A. F is more electronegative than N atom
B. In `NF_3` the orbital dipole is in the direction opposite to the resultant dipole moment of the three N-F bonds
C. In `NH_3` the orbital dipole is in the direction same to the resultant dipole moment of the three N-H bonds
D. All of the above

Answer

D
