structure?
(i) Glucose does not form hydrogen sulphite with 
.

(i) Free aldehyde group doesn't exist in glucose due to its cyclic structure. Hence, it doesn't
react with 
.
(ii) On oxidation with conc. 
, glucose gives saccharic acid. This property can be explained by open-chain structure of glucose.
(iii) The phenomenon of existence saccharic acid of glucose in two crystalline forms can only be explained by difference in configuration of 
group at anomeric carbon.
