Answer
C. Gluconic acid
Step-by-step solution
Bromine water is a mild oxidizing agent. When glucose reacts with bromine water, the aldehyde group (-CHO) is oxidized to a carboxylic acid group (-COOH), while the hydroxyl groups remain unaffected. The reaction is given by: CHO-(CHOH)_4-CH_2OH + Br_2/H_2O COOH-(CHOH)_4-CH_2OH The product formed is gluconic acid. Answer: Gluconic acid
