Vedclass · Answer

(A) $1$. Identify the principal functional group: The aldehyde group $(-CHO)$ has the highest priority,so the parent chain must include the carbon of the $-CHO$ group and it is numbered as $C-1$.$2$. Select the longest carbon chain containing the principal functional group: The longest chain containing the $-CHO$ group has $5$ carbon atoms,so the parent alkane is pentane.$3$. Number the chain: The aldehyde carbon is $C-1$. The chain is numbered as $C-1$ (aldehyde),$C-2$ $(-OH)$,$C-3$ $(-OH)$,$C-4$ $(-CH_3)$,and $C-5$ (terminal methyl).$4$. Identify substituents: There are two hydroxyl groups $(-OH)$ at positions $2$ and $3$,and a methyl group $(-CH_3)$ at position $4$.$5$. Combine the parts: The name is $2, 3-$dihydroxy$-4-$methylpentanal.
