NEET Chemistry Ionic Bond MCQ Question
What is the dipole moment of the BeF2 molecule, given that the dipole moments of NH3 and NF3 are 4.90 × 10 –30 C m and 0.8 × 10 –30 C m respectively?
0 C m
4.90 × 10 –30 C m
0.8 × 10 –30 C m
6.17 × 10 –30 C m
Correct Answer
Detailed Explanation
The dipole moment of BeF2 is zero because the two equal bond dipoles point in opposite directions and cancel each other out, as stated in the NCERT context.
