Chapter 10, Problem 35P

Interpretation Introduction

Interpretation:

The reason for the enhance rate of substitution at C5 in $2,2-$ dimethyl hexane is to be explained.

Concept Introduction:

The breaking of a covalent bond in a way that each atom takes one electron from the shared pair is called homolytic fission.

Homolytic fission results in the formation of a radical, and the order of stability of the radical is as follows:

$1^{\text{o}}<2^{\text{o}}<3^{\text{o}}$

Free radical halogenation is a reaction that substitutes a chlorine for a hydrogen on an alkane. This reaction is a photochemical one. That is, it occurs only when performed in the presence of uv light

Free radical reactions are described in three steps: initiation steps, propagation steps, and termination steps
