Vedclass · Answer

(B) The principal functional group is the aldehyde $(-CHO)$,which is assigned the lowest locant $(1)$.The longest carbon chain containing the aldehyde group has $5$ carbon atoms,so the parent alkane is pentane.Numbering starts from the aldehyde carbon as $C-1$.The methyl group $(-CH_3)$ is at position $C-4$ and the hydroxyl group $(-OH)$ is at position $C-2$.Alphabetically,'hydroxy' precedes 'methyl'.Therefore,the correct $IUPAC$ name is $2-$hydroxy$-4-$methylpentanal.
