Oxidation of glucose with bromine water gives (-COOH at C1): 
AFructose
BGluconic acid
CSaccharic acid
DSorbitol
Answer & Solution
Correct answer: B. Gluconic acid
Br₂/H₂O: mild oxidant. Oxidizes only the aldehyde (-CHO at C1) to -COOH, giving gluconic acid. Stronger oxidation by HNO₃ also oxidizes the terminal CH₂OH (at C6) → saccharic acid (dicarboxylic).
