Chapter 8, Problem 8.57SP

Interpretation Introduction

Interpretation: The reaction-energy diagram showing the curves for the two possible pathways for ionic addition of $\text{HBr}$ to $1-\text{methylcyclohexene}$ and an explanation corresponding to the curves that show $1-\text{bromo}-1-\text{methylcyclohexane}$ are formed faster is to be stated.

Concept introduction: The steps followed by electrophilic addition reaction are stated below:

• First protonation of the alkene takes place to generate the carbocation.
• The halide ion will attack on the carbocation to give the final product.

To determine: The reaction-energy diagram showing the curves for the two possible pathways for ionic addition of $\text{HBr}$ to $1-\text{methylcyclohexene}$ and an explanation corresponding to the curves that show $1-\text{bromo}-1-\text{methylcyclohexane}$ is formed faster.
