Question

The electronegativity difference between N and F is greater than N and H, yet the dipole moment of $N{H}_3$ (1.5 D) is greater than that of $N{F}_3$ (0.2 D). This is because:

• A. In $N{H}_3$ as well as $N{F}_3$, the overall molecular dipole and bond dipoles are in the opposite direction
• B. In $N{H}_3$, the overall molecular dipole and bond dipoles are in the opposite direction, whereas in $N{F}_3$, these are in the same direction.
• C. In $N{H}_3$ as well as in $N{F}_3$ the overall molecular dipole and bond dipoles are in the same direction
• D. In $N{H}_3$, the overall molecular dipole and bond dipoles are in the same direction, whereas in $N{F}_3$ these are in the opposite direction

Answer 1

The correct option is D In $N{H}_3$, the overall molecular dipole and bond dipoles are in the same direction, whereas in $N{F}_3$ these are in the opposite direction

In $N{H}_3$, the overall molecular dipole and bond dipoles are in the same direction,
whereas in $N{F}_3$ these are in the opposite direction:
