Chapter 6, Problem 6.41SP

(a)

Interpretation Introduction

To determine: The validation corresponding to the fact that first-order ionization of an allylic halide leads to a resonance-stabilized cation.

Interpretation: The validation corresponding to the fact that first-order ionization of an allylic halide leads to a resonance-stabilized cation is to be predicted.

Concept introduction: A group in which carbon atom that is attached to the double bond carries one or more than one halogen group is known as allylic halide group.

If a molecular compound dissociates to give ions, then this is called the ionization of that compound.

(b)

Interpretation Introduction

To draw: The resonance structures of the allylic cation that are formed by the ionization of the given halides.

Interpretation: The resonance structures of the allylic cation that are formed by the ionization of the given halides are to be drawn.

Concept introduction: A group in which carbon atom that is attached to the double bond carries one or more than one halogen group is known as allylic halide group.

If a molecular compound dissociates to give ions, then this is called the ionization of that compound.

(c)

Interpretation Introduction

To determine: The expected products that are obtained by the ${\text{S}}_{\text{N}}1$ solvolysis of the given halides.

Interpretation: The expected products that are obtained by the ${\text{S}}_{\text{N}}1$ solvolysis of the given halides are to be shown.

Concept introduction: A group in which carbon atom that is attached to the double bond carries one or more than one halogen group is known as allylic halide group.

The nucleophilic reaction that contains only a substrate as a reactant not a nucleophile, which means a unimolecular nucleophilic reaction is termed as ${\text{S}}_{\text{N}}1$ reaction.
