Question

Reaction of ethanol with conc. Sulphuric acid at 170${}^{\circ }$C produces a gas which is then treated with bromine in carbon tetrachloride. The major product obtained in this reaction is :

• A. 1,2-dibromoethane
• B. ethylene glycol
• C. bromoethane
• D. ethyl sulphate

Answer 1

The correct option is A

1,2-dibromoethane

$C{H}_3-C{H}_2-OH\underset{{170}^{\circ }}{\overset{Conc{H}_{2}S{O}_4}{\to }}\underset{Ethene}{C{H}_2=C{H}_2}\underset{CC{l}_4}{\overset{B{r}_2}{\to }}\underset{1,2-Dibromoethene}{\underset{}{\underset{Br}{\overset{}{\underset{|}{\overset{}{C{H}_2-}}}}}\underset{}{\underset{Br}{\overset{}{\underset{|}{\overset{}{C{H}_2}}}}}}$
