Glucose fails to react with sodium hydrogen sulphite

Vedclass · Answer

(C) The open-chain structure of glucose contains an aldehyde group $(-CHO)$.Typically,aldehydes react with sodium hydrogen sulphite $(NaHSO_3)$ to form addition products.However,glucose does not react with $NaHSO_3$,which indicates that the aldehyde group is not free.This suggests that the aldehyde group is involved in the formation of a cyclic hemiacetal structure,confirming that glucose exists as a cyclic compound in its stable form.
