Vedclass · Answer

(B) The given structure is $CH_3-CH=CH-C\equiv CH$.According to $IUPAC$ rules,the principal functional group is the one that gets the lowest possible locant.Numbering from the right side gives the triple bond position $1$ and the double bond position $3$.Numbering from the left side gives the double bond position $2$ and the triple bond position $4$.Comparing the sets of locants $(1, 3)$ and $(2, 4)$,the set $(1, 3)$ is lower.Therefore,the parent chain is $Pent$ and the name is $Pent-3-en-1-yne$.Hence,the correct option is $B$.
