Vedclass · Answer

(B) $1$. Identify the principal functional group: The carboxylic acid group $(-COOH)$ has higher priority than the ketone group $(C=O)$. Thus,the parent chain is named as an alkanoic acid.$2$. Number the chain: Start numbering from the carbon of the $-COOH$ group as $C-1$. The chain is numbered as follows: $C-1$ $(-COOH)$,$C-2$ $(-CH(CH_3)-)$,$C-3$ $(-CH_2-)$,$C-4$ $(-CH_2-)$,$C-5$ $(C=O)$,$C-6$ $(-CH_3)$.$3$. Identify substituents and functional groups: There is a methyl group at position $2$ and a ketone group at position $5$. The ketone group is named as an 'oxo' substituent.$4$. Assemble the name: $2-$Methyl$-5-$oxohexanoic acid.
