MCQ
The correct order of dipole moment is
  • $C{H_4} < N{F_3} < N{H_3} < {H_2}O$
  • B
    $N{F_3} < C{H_4} < N{H_3} < {H_2}O$
  • C
    $N{H_3} < N{F_3} < C{H_4} < {H_2}O$
  • D
    ${H_2}O < N{H_3} < N{F_3} < C{H_4}$

Answer

Correct option: A.
$C{H_4} < N{F_3} < N{H_3} < {H_2}O$
(a)The dipole moment of $C{H_4} = 0\,D,$

$N{F_3} = 0.2\,D,\,\,N{H_3} = 1.47\,D$

and ${H_2}O = 1.85\,D$.

Therefore the correct order of the dipole moment is

$C{H_4} < N{F_3} < N{H_3} < {H_2}O$.
