Vedclass · Answer

(A) Photochlorination involves the substitution of a hydrogen atom with a chlorine atom. Diastereomers are stereoisomers that are not mirror images of each other. For a compound to produce diastereomers upon chlorination,it must already contain at least one chiral center,and the chlorination must occur at a position that creates a second chiral center.$1$. Consider $3-$methylhexane: The structure is $CH_3-CH_2-CH(CH_3)-CH_2-CH_2-CH_3$. It has a chiral center at $C3$. Upon photochlorination,substitution at different positions (like $C2$ or $C4$) creates a new chiral center,resulting in diastereomeric pairs.$2$. $2-$chlorobutane already has a chiral center,but chlorination would create a dichlorobutane derivative which is not the smallest hydrocarbon precursor.$3$. $1-$bromopropane and $1-$bromo$-3-$methylbutane do not satisfy the requirement of being the smallest hydrocarbon capable of generating diastereomers through this specific mechanism.Thus,$3-$methylhexane is the smallest alkane that produces diastereomers upon photochlorination.
