Glucose forms an addition product with $NaHSO_3$.

Vedclass · Answer

(D) The correct answer is $D$. Glucose is an aldohexose containing a free aldehyde group,but it does not form an addition product with $NaHSO_3$ because the aldehyde group is involved in the formation of a cyclic hemiacetal structure. Option $A$ is correct because glucose does not restore the pink color of Schiff's reagent. Option $B$ is correct as glucose exists in $\alpha-$ and $\beta-$ anomeric forms. Option $C$ is correct because the pentaacetate of glucose lacks a free $-OH$ group at the $C-1$ position,preventing the formation of the open-chain aldehyde required to react with $NH_2OH$.
