Detailed explanation-1: -Glucose undergoes an oxidation reaction to give gluconic acid in the presence of bromine water solution. Bromine water is a mild oxidizing agent which selectively oxidizes aldehyde to carboxylic acid only. It doesn’t oxidize alcohol or ketone.

Detailed explanation-2: -bromine water is mild oxidizing agent and oxidation of glucose with bromine water to gluconic acid shows that the carbonyl group in glucose is aldehyde group.

Detailed explanation-3: -Glucose on reaction with bromine water gives Gluconic acid. Aldehyde group is oxidized to carboxylic group.

Detailed explanation-4: -Gluconic acid can be prepared by oxidation of glucose with H2O2 and could be of practical food and medicine applications. Gluconic acid and its salts are important compounds that are extensively used in pharmaceutical, food and chemical industries.

Detailed explanation-5: -Glucose is converted into gluconic acid by oxidation with oxygen in aqueous solution, by a process comprising passing a glucose containing aqueous solution over a catalyst which contains glucose oxidase and catalase, bound to an appropriate carrier, in immediate proximity to one another.
