$2,3-$dimethylbutane

Vedclass · Answer

(A) $2,3-$dimethylbutane $(CH_3-CH(CH_3)-CH(CH_3)-CH_3)$ contains two types of equivalent hydrogen atoms: primary $(CH_3)$ and tertiary $(CH)$.Substitution of a hydrogen atom from the primary carbon leads to $1-$chloro-$2,3-$dimethylbutane.Substitution of a hydrogen atom from the tertiary carbon leads to $2-$chloro-$2,3-$dimethylbutane.Since there are only two distinct types of hydrogen atoms,it yields exactly two isomeric monochloro derivatives.

Which of the following will give two isomeric monochloro derivatives?
