Question
17. The electronegativity difference between N & F is greater than that between N & H. Yet the dipole moment of NH3 is 1.5D. This is because: 1. In NH3 the atomic dipole and bond dipole are in the opposite directions whereas in NF3, these are in the same direction. 2. In NH3 as well as in as well as in NF3, the atomic dipole and bond dipole are in the same direction. 3. In NH3 the atomic dipole and dipole at in the same direction whereas in NF3 these are in opposite directions. 4. In NH3 as well as in NF3, the atomic dipole and the bond dipole are in opposite directions.
