Vedclass · Answer

(C) The structure is $CH_3-CO-CH(CH_3)-CH(CHO)-CH(CH_3)_2$. According to $IUPAC$ rules,the aldehyde group $(-CHO)$ has higher priority than the ketone group $(>C=O)$. Thus,the parent chain is the longest chain containing the $-CHO$ group,which consists of $5$ carbons. The carbon of the $-CHO$ group is numbered as $C1$. The substituents are: an isopropyl group at $C2$,a methyl group at $C3$,and an oxo group at $C4$. Combining these,the name is $2-Isopropyl-3-methyl-4-oxopentanal$.

The $IUPAC$ name of the compound $CH_3-CO-CH(CH_3)-CH(CHO)-CH(CH_3)_2$ is:
