उत्तर
(i) 2-Bromopentane
(iv) Trichloromethane
Explanation:
\[\begin{array}{cc}
\ce{CH3CHCH2CH2CH3}\\

\[\begin{array}{cc}
\ce{Cl - CH - Cl}\\
\phantom{}|\phantom{..}\\
\phantom{}\ce{\underset{Trichloromethane}{Cl}}\phantom{.}
\end{array}\]
In both of these compounds halogen atoms are attached to sp3 hybridised carbon atom of alkyl group.
