→Glucose HNO3−−−→dicarboxylic acid
shows the presence of−CH2OH group in glucose.
→GlucoseAcetic anhydride−−−−−−−−−→ Glucose pentacetateshows presence of 5−OHgroup in glucose.
→Glucose in the presence ofmild oxidising reagent like Tollen's reagent givescarboxylic acid which showsthe presence of aldehyde group.
→On heating glucose with HI ,it gives n−hexane which shows the presence of linearly linked 6 carbons in glucose.
