Question

Consider the dipole moments of $N{H}_3$ and $N{F}_3$. Which of the following is correct?

• A. Dipole moment of NF₃ is equal to that of NH₃
• B. Dipole moment of NH₃ is equal in magnitude but opposite in sign to that of NF₃
• C. Dipole moment of NF₃ is more than that of NH₃
• D. Dipole moment of NH₃ is more than that of NF₃

Answer 1

The correct option is D

Dipole moment of NH₃ is more than that of NF₃

In $N{F}_3$ bond moments acts opposite directions so it has lower dipole moment
