Chapter 13, Problem 57P

Interpretation Introduction

Interpretation: An explanation for the different products obtained by the reaction of $3,3$-dimethylbut-$1$-ene with $\text{HBr}$ alone and with $\text{HBr}+\text{peroxide}$ is to be stated.

Concept introduction: Alkenes and alkynes show addition reaction due to presence of one and two pi-bonds, respectively. Alkanes show substitution reaction due to absence of pi-bond. The addition reaction of alkenes with $\text{HBr}$ takes place according to Markovnikov and anti-Markovnikov rule.
