Vedclass · Answer

(C) The catalytic reduction of an alkene with $H_2 / Pt$ involves the addition of hydrogen across the double bond to form the corresponding alkane.To obtain $n$-butane $(CH_3-CH_2-CH_2-CH_3)$,the starting alkene must have a four-carbon straight chain.The possible alkenes with a four-carbon straight chain are:$1$. $1$-butene $(CH_2=CH-CH_2-CH_3)$$2$. $cis$-$2$-butene $(CH_3-CH=CH-CH_3)$$3$. $trans$-$2$-butene $(CH_3-CH=CH-CH_3)$All three of these alkenes,upon hydrogenation,yield $n$-butane.Therefore,there are $3$ such alkenes.

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