Chapter 12.22, Problem 32P

Interpretation Introduction

Interpretation:

The second resonance contributor for imidazolium ion that obeys the octet rule and has a positive charge on the other nitrogen atom is to be drawn.

Concept introduction:

On the basis of octet rule Lewis formulas are written, which limits second-row elements to have no more than eight electrons in their valence shells.

The two Lewis structures are resonance contributors, if the connectivity of atoms is the same. Each contributing structure should have the same number of total electrons and the net charge.

For each resonance contributor, the octet rule must be obeyed.

The flow of electrons is indicated by curly arrows.
