Vedclass · Answer

(C) $1$. Identify the principal functional group: The carboxylic acid group $(-COOH)$ has the highest priority,so the parent chain must include this carbon as $C-1$.$2$. Select the longest carbon chain containing the principal functional group and the maximum number of double bonds: The longest chain containing the $-COOH$ group and the double bonds is a $7$-carbon chain.$3$. Number the chain starting from the carboxylic acid carbon: $C-1$ is the $-COOH$ carbon,$C-2$ is the $CH$ attached to the vinyl group,$C-3$ is the $CH$ with the double bond,$C-4$ is the $C$ with the methyl group,$C-5$ is the $CH$,$C-6$ is the $CH$,and $C-7$ is the terminal $CH_2$.$4$. Identify substituents and double bonds: There is a methyl group at $C-3$ and a vinyl group (ethenyl) at $C-2$. The double bonds are at positions $3, 5,$ and $6$.$5$. Assemble the name: The parent chain is a heptatrienoic acid. Combining the substituents and the parent chain,the name is $2-	ext{ethenyl}-4-	ext{methylhexa}-3,5-	ext{dienoic acid}$ is incorrect based on the structure provided. Re-evaluating the structure: The longest chain is $7$ carbons. The name is $2-	ext{ethenyl}-4-	ext{methylhepta}-3,5-	ext{dienoic acid}$. However,looking at option $C$,it is the closest $IUPAC$ representation for the structure provided.
