Question

Equation for the reaction when compound $A$ is bubbled through bromine dissolved in carbon tetrachloride is as follows :
$A\underrightarrow{B{r}_2/C{Cl}_4}\begin{array}{c}C{H}_{2}Br\\ |\\ C{H}_{2}Br\end{array}$
(i) Draw the structure of $A$.
(ii) State your observation during this reaction.

Answer 1

$H-\stackrel{H}{\stackrel{|}{C}}=\stackrel{H}{\stackrel{|}{C}}-H$

(i) Compound A is ethene.

(ii) Brown colour of bromine is discharged. It serves as a test for unsaturation.
