Vedclass · Answer

(A) The given structure is $CH_3-C \equiv C-CH(CH_3)_2$.To determine the $IUPAC$ name,we first identify the longest carbon chain containing the triple bond.The longest chain has $5$ carbon atoms,so the parent alkane is pentane,and with the triple bond,it becomes pentyne.Numbering the chain from the left gives the triple bond the lowest possible locant,which is $2$.There is a methyl group attached to the $4^{th}$ carbon.Thus,the correct $IUPAC$ name is $4-$methylpent$-2-$yne.Therefore,the correct option is $(A)$.

The $IUPAC$ name of $CH_3C \equiv CCH(CH_3)_2$ is
