Chapter 3, Problem 3.39P
Interpretation Introduction

Interpretation:

The number of π bonds in the given Lewis structure of β-carotene is to be determined.

Concept introduction:

The molecule of a compound is formed by covalent bond formation between two atoms. There are two types of covalent bonds – π bond and σ bond. CC bond is considered as σ bond, and C=C bond is composed of one π bond and one σ bond. Therefore, each C=C bond is counted as one π bond.
