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

Short/Brief Note

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.
