Which of the following molecules does not show any resonating structures?

A$$NH_3$$
Correct Answer
B$$CO_3{^{2-}}$$
C$$O_3$$
D$$SO_3$$

Solution

Resonance is shown by the molecules which have these type of system:-
-Adjacent double bond and positive charge
-Adjacent double bond and negative charge
-Adjacent lone pair and double bond
- Adjacent double bond and free radical
-Two adjacent double bond
-Adjacent lone pair and positive charge.
$$NH_3$$ does not have any such kind of system where resonance is possible.
So the correct answer is the option [A]
