Chapter 10.3, Problem 4P

Interpretation Introduction

Interpretation:

The equations of initiation and propagation steps for the formation of $\text{dichloromethane}$ by free-radical chlorination of $\text{chloromethane}$ are to be written.

Concept introduction:

>

The breaking of a covalent bond between two atoms in a way that each atom retains one of the electrons from the bond is called homolytic cleavage.

>

The breaking of a covalent bond between two atoms in a way that one of theatomsretainsboth the electrons from the bond is called heterolytic cleavage.

>

The movement of a single electron is shown by a Fishhook arrow andis also called as a single electron.

>

Initiation describes the initial step of the formation of radicals.

>

Propagation is the chain of radical reactions. Once the radical is formed in the initiation step, it reacts with suitable molecules.
