Vedclass · Answer

(D) Let us analyze each option:$A$: $CH_3-CH_2-CH_2-COOCH_2CH_3$ is an ester. The alkyl group attached to oxygen is ethyl, and the acid part is butanoate. The name is correct.$B$: $CH_3-CH(CH_3)-CH_2-CHO$. The longest chain has $4$ carbons. The methyl group is at position $3$. The name $3$-methylbutanal is correct.$C$: $CH_3-CH(OH)-CH(CH_3)-CH_3$. The longest chain has $4$ carbons. The hydroxyl group is at position $2$ and the methyl group is at position $3$. The name $3$-methylbutan-$2$-ol is correct.$D$: $CH_3-CH(CH_3)-CO-CH_2-CH_3$. The longest chain has $5$ carbons. The ketone group is at position $3$. According to the lowest locant rule, numbering should start from the left to give the methyl group the lower number $(2)$. Thus, the correct name is $2$-methylpentan-$3$-one, not $4$-methylpentan-$3$-one. Therefore, the name given in option $D$ is incorrect.
