The electronegativity difference between N and F is greater than that between N and H yet the dipole moment of NH3 (1.5 D) is larger than that of NF3 (0.2 D). This is because:

(1) in NH3 as well as in NF3 the atomic dipole and bond dipole are in the same direction
(2) in NH3 the atomic dipole and bond dipole are in the same direction whereas in NFthese are in opposite directions
(3) in NH3 as well as NF3 the atomic dipole and bond dipole are in opposite directions
(4) in NH3 the atomic dipole and bond dipole are in the opposite directions whereas in NF3 these are in the same directions
