Question

Name the products formed and write an equation when ethyne is added to the following in an inert solvent:

Bromine

Answer 1

When bromine, in carbon tetrachloride, is added to ethyne, its reddish brown colour disappears due to the formation of addition products.

\[\ce{\underset{Ethyne}{C2H2} ->[+Br2][(from CBr4)] \underset{1, 2-dibromoethene}{C2H2Br2} ->[+Br2][(from CBr4)] \underset{1, 1, 2, 2-tetrabromo ethane}{C2H2Br4}}\]
