Q. $CH_{3}CH_{3} + HNO_{3}\overset{675\ K\ \ \ \ \ }{\rightarrow}$ ?
A) $CH_{3}CH_{2}NO_{2}$
B) $CH_{3}CH_{2}NO_{2} + CH_{3}NO_{2}$
C) $2CH_{3}NO_{2}$
D) $CH_{2} = CH_{2}$
Explanation
(b)
Ethane gives a mixture of nitroethane and nitromethane.
$CH_{3} - CH_{3} + {HNO}_{3}$
Ethane
$\underset{- H_{2}O}{\overset{\ \ \ \ 673\ K\ \ \ \ }{\rightarrow}}CH_{3} - CH_{2} - NO_{2} + CH_{3}NO_{2}$
nitro ethane (minor)
(major)
During nitration chain fission of alkanes also takes place, so $CH_{3}NO_{2}$ is also obtained along with $CH_{3}CH_{2}NO_{2}$.
