The electronegativity difference between N and F is greater than that between N and H yet the dipole mement of NH3 (5 is larger than that of NF3 (0.2 . This is because__________

in NH3 the atomic dipole and bond dipole are in the opposite directions whereas in NF3 these are in the same direction
in NH3 as well as in NF3 the atomic dipole and bond dipole are in the same direction
in NH3 the atomic dipole and bond dipole are in the same direction whereas in NF3 these are in opposite directions
in NH3 as well as NF3 the atomic dipole and bond dipole are in opposite directions
