1. Reaction with HCNHCN, or with hydroxlyamine (NH2OHNHX2OH)
Glucose reacts with HCNHCN to give a cyanohydrin, or with a schiffs base to give an oxime. This shows the presence of a carbonyl group.
2. Reaction with acetic anhydride (CH3CO)2O(CHX3CO)X2O
Glucose gives a penta ester with acetic anhydride, revealing that it has 5 hydroxyl groups.
3. Reaction with Nitric acid
On oxidation with Nitric acid (HNO3HNOX3),glucose as well as gluconic acid both yeild a dicarboxylic acid (saccharic acid). This indicates the presence of a primary alcoholic group in glucose.
