$CH_3-C(=O)-CH(CH_3)_2$: $2$-methylbutan-$3$-one

Vedclass · Answer

(A) Let us analyze each option:$A$. The structure $CH_3-C(=O)-CH(CH_3)_2$ is $3$-methylbutan-$2$-one,not $2$-methylbutan-$3$-one. The numbering should start from the end closer to the ketone group.$B$. The structure $CH_3-CH(CH_3)-CH(CH_3)-CH_2-CH_3$ is correctly named $2,3$-dimethylpentane.$C$. The structure $CH_3-C \equiv C-CH(CH_3)_2$ is correctly named $4$-methylpent-$2$-yne.$D$. The structure $CH_3-CH(Cl)-CH(Br)-CH_3$ is named alphabetically as $3$-bromo-$2$-chlorobutane,not $2$-bromo-$3$-chlorobutane. However,in many contexts,option $A$ is the most fundamentally incorrect due to the numbering priority of the functional group.
