Question
Haloalkanes contain halogen atom (s) attached to the sp3 hybridised carbon atom of an alkyl group. Identify haloalkane from the following compounds.
(i) 2-Bromopentane
(ii) Vinyl chloride (chloroethene)
(iii) 2-chloroacetophenone
(iv) Trichloromethane

Solution
(i) 2-Bromopentane
(iv) Trichloromethane
Explanation:
\[\begin{array}{cc}
\ce{CH3CHCH2CH2CH3}\\
\phantom{}|\phantom{..........}\\
\phantom{}\ce{\underset{2-Bromopentane}{Br}}\phantom{.........}
\end{array}\]
\[\begin{array}{cc}
\ce{Cl - CH - Cl}\\
\phantom{}|\phantom{..}\\
\phantom{}\ce{\underset{Trichloromethane}{Cl}}\phantom{.}
\end{array}\]
In both of these compounds halogen atoms are attached to sp3 hybridised carbon atom of alkyl group.
