Question

Equation for the reaction when compound A is bubbled through bromine dissolved in carbon tetrachloride is as follows:

\[\begin{array}{cc}
\ce{A ->[Br2/CCl4] CH2Br}\\
\phantom{.........}|\\
\phantom{.................}\ce{CH2Br}\\
\end{array}\]

1. Draw the structure of compound A.
2. State your observation during this reaction.

Answer 1

1. \[\ce{CH2 = CH2}\]
2. When bromine dissolved in CCl4 is added to ethene, the orange colour disappears because it forms colourless ethylene bromide.
