All of these

Vedclass · Answer

(D) Catalytic hydrogenation $(H_2/Ni)$ of alkenes involves the syn-addition of hydrogen across the double bond. $(a)$ $4-$methylmethylenecyclohexane on hydrogenation yields both $cis-1,4-$dimethylcyclohexane and $trans-1,4-$dimethylcyclohexane due to the approach of $H_2$ from either face of the ring. $(b)$ $1,4-$dimethylcyclohex$-1-$ene similarly yields both $cis$ and $trans$ isomers of $1,4-$dimethylcyclohexane. $(c)$ $3,3,6-$trimethylcyclohex$-1-$ene also produces stereoisomeric products upon hydrogenation. Since all the given alkenes can produce $cis$ and $trans$ isomers (or diastereomers) upon catalytic hydrogenation, the correct answer is 'All of these'.

Which of the following alkenes gives both $cis$ and $trans$ isomers upon catalytic hydrogenation?
