NEET Chemistry Ionic Bond MCQ Question
Which of the following statements regarding the dipole moment of NH3 and NF3 is correct?
NH3 has a higher dipole moment than NF3 due to the direction of the lone pair's orbital dipole.
NF3 has a higher dipole moment than NH3 because its N-F bonds are more polar.
Both NH3 and NF3 have identical dipole moments due to their similar molecular structures.
The lone pair in NH3 reduces its dipole moment, making it lower than that of NF3.
Correct Answer
Detailed Explanation
NH3 has a higher dipole moment than NF3 because the orbital dipole of the lone pair in NH3 is in the same direction as the resultant dipole moment of the N-H bonds, whereas in NF3, it is opposite to the resultant N-F bond moments.
