MCQ

Propene when heated with chlorine at about ${500\,^o}C$ forms

✓
$C{H_2}Cl.CH = C{H_2}$
B
$C{H_3}.CHCl.C{H_2}Cl$
C
$C{H_2}Cl.CHCl.C{H_2}Cl$
D
All the three

✓

Answer

Correct option: A.

$C{H_2}Cl.CH = C{H_2}$

a
(a) $C{H_3} - CH = C{H_2} + C{l_2}\xrightarrow{{500{\,^o}C}}$ $\begin{array}{*{20}{c}}
{C{H_2} - CH = C{H_2}} \\
{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\
{Cl\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}
\end{array} + HCl$

This reaction is called allylic halogenation reaction because halogenation occurs at the allylic position of an alkene
