Vedclass · Answer

(B) $1$. 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 assigned position $1$.$2$. Select the longest carbon chain containing the principal functional group: The chain has $5$ carbons,so the parent alkane is pentane. The suffix for aldehyde is $-al$,so the parent name is pentanal.$3$. Number the chain: The carbon of the $-CHO$ group is $C-1$. The methyl group $(-CH_3)$ is at $C-4$ and the hydroxyl group $(-OH)$ is at $C-4$.$4$. Assemble the name: The substituents are $4-$hydroxy and $4-$methyl. Alphabetically,'h' comes before 'm'. Thus,the name is $4-$hydroxy$-4-$methylpentanal. However,re-evaluating the structure $CH_3-CH(OH)-CH_2-CH(CH_3)-CHO$: The chain is $C_1(CHO)-C_2(H)(CH_3)-C_3(H_2)-C_4(H)(OH)-C_5(H_3)$. The substituents are at position $4$ (hydroxy) and position $2$ (methyl). Therefore,the correct name is $4-$hydroxy$-2-$methylpentanal.
