Chapter 23, Problem 110SCQ

Interpretation Introduction

Interpretation: Another resonance structure of pyridine has to be drawn and also the similarities between benzene and pyridine has to be stated.

Concept introduction:

• Sometimes the chemical bonding of a molecule cannot be represented using a single Lewis structure. In these cases, the chemical bonding are described by delocalization of electrons and is known as resonance.
• All the possible resonance structures are imaginary whereas the resonance hybrid is real.
• These structures will differ only in the arrangement of the electrons not in the relative position of the atomic nuclei
• Benzene as well as pyridine both have six membered ring where all the atoms are ${\text{sp}}^{\text{2}}$ hybridized
