The correct order of dipole moment is
The correct order of dipole moment is
Options
- A(\mathrm{CH}_4 < \mathrm{NF}_3 < \mathrm{NH}_3 < \mathrm{H}_2 \mathrm{O})
- B(\mathrm{NF}_3 < \mathrm{CH}_4 < \mathrm{NH}_3 < \mathrm{H}_2 \mathrm{O})
- C(\mathrm{NH}_3 < \mathrm{NF}_3 < \mathrm{CH}_4 < \mathrm{H}_2 \mathrm{O})
- D(\mathrm{H}_2 \mathrm{O} < \mathrm{NH}_3 < \mathrm{NF}_3 < \mathrm{CH}_4).
Correct answer
A. (\mathrm{CH}_4 < \mathrm{NF}_3 < \mathrm{NH}_3 < \mathrm{H}_2 \mathrm{O})
Step-by-step solution
In , electronegativity difference is highest. So, dipole moment is highest in this. is a symmetrical tetrahedral structure and its dipole moment is zero.
