AIPMT 2006 | Chemical Bonding and Molecular Structure Question 91 | Chemistry

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

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 in NF₃ the atomic dipole and bond dipole are in opposite directions.
