Chapter 9, Problem 41DSP

Interpretation Introduction

Interpretation:

The general statement that can be made regarding cyclic bromonium ion that is produced during the rate-determining step of addition reaction of bromine molecule to alkynes is to be determined.

Concept Introduction:

Alkynes are produced by both electrophilic and nucleophilic reaction. During the electrophilic reaction, the E2 reaction mechanism pathway is followed and in nucleophilic, ${\text{S}}_{\text{N}}2$ mechanism is followed. Alkynes are associated with triple bond therefore; their properties are vastly different for that of alkene and alkane. Alkynes have high electron density hence, favors electrophilic addition reaction.
