Vedclass · Answer

(D) Catalytic hydrogenation of an alkyne involves the addition of hydrogen across the triple bond to form the corresponding alkane. $3$-ethylhexane has the molecular formula $C_8H_{18}$. All the given alkynes ($3$-ethylhex-$1$-yne,$4$-ethylhex-$1$-yne,and $3$-ethylhex-$3$-yne) have the same carbon skeleton as $3$-ethylhexane. Therefore,upon complete catalytic hydrogenation,all of them will yield $3$-ethylhexane as the final product. Thus,the correct option is $D$.

Which alkyne will give $3$-ethylhexane on catalytic hydrogenation?
