Vedclass · Answer

(D) The double bond is given priority over the triple bond when numbering the carbon chain.Numbering starts from the end that gives the double bond the lowest possible locant.Thus,the chain is numbered from left to right: $\stackrel{1}{CH_2}=\stackrel{2}{CH}-\stackrel{3}{CH_2}-\stackrel{4}{CH_2}-\stackrel{5}{C}\equiv\stackrel{6}{CH}$.The parent chain has $6$ carbons,so the root is 'hex'.The double bond is at position $1$ and the triple bond is at position $5$.Therefore,the $IUPAC$ name is $1-$hexene$-5-$yne.
