Chapter 15, Problem 15.28P

Interpretation Introduction

(a)

Interpretation: The constitutional isomers formed by the monochlorination of given alkanes with ${\text{Cl}}_{\text{2}}$ and $hv$ is to be drawn.

Concept introduction: The compounds with same chemical formula but different arrangement of atoms in space are known as the constitutional isomers.

The reaction of halogen with alkane results in the formation of alkyl halide. This type of reaction is a radical substitution reaction. The halogenation of alkanes takes place via radical intermediates. If $\text{C}-\text{H}$ bond is weaker than hydrogen is replaced more readily.

Interpretation Introduction

(b)

Interpretation: The major bromination product formed by heating each alkane with ${\text{Br}}_{\text{2}}$ is to be drawn.

Concept introduction: The reaction of hydrogen halide with alkane results in the formation of alkyl halide. The halogenation of alkanes takes place via radical intermediates. If $\text{C}-\text{H}$ bond is weaker than hydrogen is replaced more readily.
