The electronegativity difference berween N and F is greater than that between N and H yet the dipole moment of NH3 (1.5D) is larger than that of NF3 (0.2 D). This is because
A
in NH3 the atomic dipole and bond dipole are in the opposite directions whereas in NF3 these are in the same direction
B
in NH3 as well as in NF3 the atomic dipole and bond dipole are in the same direction
C
in NH3 the atomic dipole and bond dipole are in the same direction whereas in NF3 these are in opposite directions
D
in NH3 as well as in NF3 the atomic dipole and bond dipole are in opposite directions.
