# How many resonance structures are there for NO2?

Aug 4, 2014

There are two major resonance structures for ${\text{NO}}_{2}$.

#### Explanation:

You must first draw the Lewis structure for ${\text{NO}}_{2}$.

You find that you can draw two Lewis structures.

However, there are two even better Lewis structures.

The $\text{N}$ atom has an unpaired electron and a positive charge.

Every atom has a formal charge of zero.

These are the two major resonance contributors to ${\text{NO}}_{2}$.
