NEET Chemistry Ionic Bond MCQ Question
Type: MCQ-numerical-Easy-Class 11
Which of the following statements regarding the dipole moment of NH3 and NF3 is correct?
A
NH3 has a higher dipole moment than NF3 due to the direction of the lone pair's orbital dipole.
B
NF3 has a higher dipole moment than NH3 because its N-F bonds are more polar.
C
Both NH3 and NF3 have identical dipole moments due to their similar molecular structures.
D
The lone pair in NH3 reduces its dipole moment, making it lower than that of NF3.
Correct Answer
Option A
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.
