Question

We’ll see in the next chapter that alkynes undergo many of the same reactions that alkenes do. What product might you expect from each of the following reactions?

Short answer

The reaction is an example of electrophilic addition. A brominium ion is formed when alkyne undergoes elecrophilic addition reaction.

Step-by-step solution

Introduction

The reaction is an example of electrophilic addition. A brominium ion is formed when alkyne undergoes elecrophilic addition reaction.

Chemical reaction involved

Reaction of alkyne with alkyl halide

When alkyne reacts with alkyl halide, they undergo an additional reaction to form halogen substituted alkene.Alkyne followa Markovnikov regiochemistry in which one halogen atom and one hydrogen atom are always added in a trans relationship with each other.
