Vedclass · Answer

(A) $1$. Identify the longest carbon chain containing both the double and triple bonds. The chain has $7$ carbons,so the parent alkane is heptane.$2$. Number the chain from the end that gives the lowest locants to the multiple bonds. Starting from the double bond end,the double bond is at $C-1$ and the triple bond is at $C-6$. If we start from the other end,the triple bond is at $C-1$ and the double bond is at $C-6$. According to $IUPAC$ rules,when both double and triple bonds are present,the double bond gets priority for the lowest number if they are at equivalent positions. Thus,the chain is numbered from the alkene end.$3$. The substituents are two methyl groups at positions $3$ and $5$,and a propyl group at position $4$.$4$. Combining these,the name is $3, 5-$dimethyl$-4-$propylhept$-1-$en$-6-$yne.

The $IUPAC$ name of the following compound is:
