Q. Identify Z in the series, $CH_{2} = CH_{2}\overset{\ HBr\ \ }{\rightarrow}X\overset{aq.KOH\ \ }{\rightarrow}Y\underset{I_{2}excess}{\overset{\ \ NaCO_{3}\ \ \ \ }{\rightarrow}}Z$
A) $C_{2}H_{5}I$
B) $C_{2}H_{5}OH$
C) ${CHI}_{3}$
D) ${CH}_{3}CHO$
Explanation
(c)
$H_{2}C = CH_{2}\overset{HBr}{\rightarrow}CH_{3} - CH_{2}Br$
(X)
$\overset{Aq.KOH}{\rightarrow}CH_{3} - CH_{2}OH\overset{\begin{array}{r}
Na_{2}CO_{3} \\
I_{2}excess
\end{array}}{\rightarrow}CHI_{3}$
(Y) (Z)
iodoform
