The correct Answer is:
To solve the question regarding the reaction of glucose with bromine water, we can follow these steps: ### Step 1: Understand the Reactants Glucose is a simple sugar (monosaccharide) with the molecular formula C₆H₁₂O₆. It contains an aldehyde functional group (-CHO) at one end of its structure. ### Step 2: Identify the Reaction When glucose reacts with bromine water (Br₂ in water), it undergoes an oxidation reaction. Bromine water is a mild oxidizing agent that can oxidize aldehydes to carboxylic acids. ### Step 3: Write the Reaction The aldehyde group (-CHO) in glucose will be oxidized to a carboxylic acid group (-COOH). The structure of glucose can be represented as: \[ \text{Glucose: } CH_2OH - (CHOH)_4 - CHO \] Upon reaction with bromine water, the aldehyde group will convert to a carboxylic acid, resulting in the formation of gluconic acid. ### Step 4: Determine the Product The product formed from the oxidation of glucose by bromine water is gluconic acid, which has the structure: \[ \text{Gluconic acid: } CH_2OH - (CHOH)_4 - COOH \] ### Final Answer Thus, the reaction of glucose with bromine water gives gluconic acid. ---
