Question

Which of the following molecules has the maximum dipole moment?

• A. $C{O}_2$
• B. $C{H}_4$
• C. $N{H}_3$
• D. $N{F}_3$

Answer 1

The correct option is C $N{H}_3$

$C{O}_2$ and $C{H}_4$ having zero dipole moment.

In $N{H}_3$, the dipole is acting in single direction, but in $N{F}_3$ due to high electronegativity of $F$-atom, the dipoles act in two opposite direction. Hence, the resultant dipole moment is higher for $N{H}_3$.
