six carbon ATOMS linked in straight chain
secondary alcoholic group in GLUCOSE
aldehyde group in glucose
primary alcoholic group in glucose

Solution :Glucose on oxidation with BROMINE water yields GLUCONIC acid. This REACTION confirms the presence of aldehyde group in glucose.
`{:(""CHO,,""COOH),(underset|overset|(""(CHOH)_4)+[O],overset(Br_2-H_2O)to,underset|overset|(""(CHOH)_4)),(underset"Glucose"(""CH_2OH),,underset"Gluconic acid"(""CH_2OH)):}`
Here, `Br_2-H_2O` act as an oxidising agent and led to the oxidation of glucose into gluconic acid
