Chapter 27, Problem 50E

Interpretation Introduction

Interpretation:

The conversion of the acetylene to $1,1,2,2\text{-tetrabromoethane}$ should be given.

Concept introduction:

Alkynes reacts with one bromine molecule in the presence of ${\text{CCl}}_{\text{4}}$ to form trans alkene and then further addition of one bromine molecule leads to the formation of tetrahalogenated alkane. The general reaction for the synthesis of tetrahalogenated alkane from alkyne is as follows:

Where, R is an alkyl group.
