Solution and Explanation
When D-glucose reacts with hydroxylamine (\( H_2N - OH \)), it forms an oxime. The aldehyde group of D-glucose reacts with hydroxylamine to form a stable oxime, with the general formula \( R - C = N - OH \), where R is the remainder of the glucose molecule. In this reaction, the glucose aldehyde undergoes nucleophilic addition to form the corresponding oxime.
