Chapter 3, Problem 3.20P
Interpretation Introduction

(a)

Interpretation:

The number of σ bonds, the number of π bonds, and the number of electrons occupying nonbonding MOs are to be determined for the given molecule.

Concept introduction:

In order to determine the number of σ bonds, the number of π bonds, and the number of electrons occupying nonbonding MOs, the line drawings must first be converted into the corresponding Lewis structures.

In the Lewis structure, a single bond represents an electron pair in a σ bonding MO. A double bond represents one pair in a σ bonding MO and one pair in a π bonding MO. Lone pairs are unshared and represent electrons occupying nonbonding MOs.

Interpretation Introduction

(b)
