Glucose reacts with bromine water to produce:

Glyceraldehyde Gluconic acid Saccharic acid Glutaric acid

Gluconic acid

The answer is (2) gluconic acid. Glucose reacts with bromine water to produce gluconic acid. Bromine water is a mild oxidizing agent, and it oxidizes the aldehyde group in glucose to a carboxyl group. The reaction is as follows:   Glyceraldehyde, saccharic acid, and glutaric acid are not produced in this reaction.
