(C) Catalytic hydrogenation of an alkene involves the addition of $H_2$ across the double bond to form the corresponding alkane. The carbon skeleton of the alkene remains unchanged during this process.To obtain $2-$methylbutane $(CH_3-CH(CH_3)-CH_2-CH_3)$,the starting alkene must have the same carbon skeleton.The possible alkenes that yield $2-$methylbutane upon hydrogenation are:$1$. $2-$methylbut-$1-$ene: $CH_2=C(CH_3)-CH_2-CH_3$$2$. $2-$methylbut-$2-$ene: $CH_3-C(CH_3)=CH-CH_3$$3$. $3-$methylbut-$1-$ene: $CH_2=CH-CH(CH_3)-CH_3$Thus,there are $3$ such alkenes.

On catalytic reduction $(H_2/Pt)$,how many alkenes will give $2-$methylbutane?
