Q. The reaction of ethanol with concentrated $H_{2}SO_{4}$ at room temperature gives
A) $CH_{3}CH_{2}OH_{2}^{+}HSO_{4}^{-}$
B) $CH_{3}CH_{2}OSO_{2}OH$
C) $CH_{3}CH_{2}OCH_{2}CH_{3}$
D) $H_{2}C = CH_{2}$
Explanation
(b)
When one $H_{2}SO_{4}$ reacts with ethyl alcohol at room temperature, ethyl hydrogen sulphate is formed
$CH_{3}CH_{2}OH + H_{2}SO_{4}\overset{\rightarrow}{Room\ temp\ }CH_{3}CH_{2}HSO_{4} + H_{2}O$
Ethyl hydrogen
sulphate
