Question

How many resonance structures can be drawn from the nitrate ions?

Answer 1

three resonance

Whenever it is necessary to show the structure of the nitrate ion, resonance forms 1, 2, and 3 are drawn, connected by a double-headed arrows. The three resonance forms of the nitrate ion, 1, 2, and 3, are identical, so they have the same stability and, therefore, contribute equally to the hybrid.

Answer 2

3 resonance structures
