Answer:
Option D
Explanation:
Chlorination of alkanes in presence of sunlight is not suitable for the preparation of alkyl chloride because chlorination of alkanes gives a complex mixture of isomeric mono and polyhaloalkanes, which is difficult to separate as pure compounds . Consequently, the yield of any one compound is low.
$CH_{3}CH_{2}CH_{2}CH_{3}$ $\underrightarrow{Cl_{2}/UV light}$ $CH_{3}CH_{2}CH_{2}CH_{2}Cl+CH_{3}CH_{2}CHClCH_{3}$
