Vedclass · Answer

(D) Anomers are stereoisomers that differ in configuration only at the anomeric carbon (the carbon derived from the carbonyl carbon in the open-chain form). Epimers are stereoisomers that differ in configuration at only one stereocenter other than the anomeric carbon.$1$. Comparing $I$ and $III$: Both have the same configuration at all carbons except the anomeric carbon $(C1)$. Thus,$I$ and $III$ are anomers.$2$. Comparing $I$ and $II$: Both have the same configuration at all carbons except $C4$. Thus,$I$ and $II$ are epimers.$3$. Comparing $III$ and $IV$: Both have the same configuration at all carbons except $C4$. Thus,$III$ and $IV$ are epimers.$4$. Comparing $II$ and $IV$: Both have the same configuration at all carbons except the anomeric carbon $(C1)$. Thus,$II$ and $IV$ are anomers.Therefore,the correct statement is that $I$ and $III$ are anomers,and $I$ and $II$ are epimers. The correct option is $(d)$.
