1.

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 :A. In `NH_(3)`, the atomic dipoles and bond dipoles are in the opposite directions while in `NF_(3)` these are in the same directionB. in `NH_(3)` and in `NF_(3)`, the atomic dipole and bond dipoles are in the same directionC. in `NH_(3)`, the atomic dipoles and bond dipole are in the same direction whereass in `NF_(3)` these are in opposite directionD. in `NH_(3)` as well as in `NF_(3)`, the atomic dipoles and bond dipoles are in opposite direction.
