Chapter 15, Problem 15.49P

Interpretation Introduction

(a)

Interpretation: All stereoisomers of molecular formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}{\text{Cl}}_{\text{2}}$ formed by the heating of (R)-$2$-chloropentane with ${\text{Cl}}_{\text{2}}$ are to be drawn.

Concept introduction: Alkyl halides undergo chlorination when they are treated with ${\text{Cl}}_{\text{2}}$ in the presence of light. Chlorination takes place at primary, secondary and tertiary carbon atom of alkyl halide. During free radical mechanism, planner achiral radical is formed. The attack of chlorine atom takes place from above and below the plane.

Interpretation Introduction

(b)

Interpretation: The number of different fraction that would be obtained from the given reaction is to be predicted.
