The correct order of dipole moment is
Options
- A( CH ₄ < NF ₃ < NH ₃ < H ₂ O )
- B( NF ₃ < CH ₄ < NH ₃ < H ₂ O )
- C( NH ₃ < NF ₃ < CH ₄ < H ₂ O )
- D( H ₂ O < NH ₃ < NF ₃ < CH ₄ ).
Correct answer
A. ( CH ₄ < NF ₃ < NH ₃ < H ₂ O )
Step-by-step solution
In H ₂ O , electronegativity difference is highest. So, dipole moment is highest in this. CH ₄ is a symmetrical tetrahedral structure and its dipole moment is zero.
