The electronegaivity difference between `N` and `F` is greater than that between ` N` and `H` yet the dipole moment of `NH_2` ( 1 .5 D) is larger than that of ` NF_3 ( 0. 2 D)`. This is because :

Options

A. in `NH_3` as wellas `NF_3` the atomic dipose and bond dipole are in opposite directions
B. in `NH_3` the atomic dipole and bond dipole and bond dipole are the opposite directions whereas in `NF_3` these are in the same direction .
C. I `NH_3` as well as in `NF_3` the atomic dipole and bond dipole are in the saem direction
D. in `NH_3` the atomic dipole and bond dipole are in the same direction wheras in `NF_3` these are in opposite directions .

Answer

D
