Vedclass · Answer

(C) $n$-Butane is $CH_{3}CH_{2}CH_{2}CH_{3}$.Monochlorination of $n$-butane yields $2$-chlorobutane $(CH_{3}CHClCH_{2}CH_{3})$, which contains a chiral center and is thus optically active ('$P$').Further chlorination of $2$-chlorobutane can occur at different carbon positions to form dichloro derivatives.The possible structural isomers for the dichloro products are:$1,1$-dichlorobutane$1,2$-dichlorobutane$1,3$-dichlorobutane$2,2$-dichlorobutane$2,3$-dichlorobutaneIgnoring stereoisomers, there are $5$ distinct structural isomers.

$n$-Butane on monochlorination under photochemical conditions gives an optically active compound "$P$". "$P$" on further chlorination gives dichloro compounds. The number of dichloro compounds obtained (ignore stereoisomers) is:
