(A) and (B) are :

Options

A. gluconic acid, gluconic acid
B. glucaric acid, gluconic acid
C. salt of gluconic acid, gluconic acid
D. salt of gluconic acid, glucaric acid

Answer

To solve the question, we need to determine the products (A) and (B) formed when D-glucose reacts with Tollen's reagent and bromine water, respectively.

### Step 1: Understanding D-Glucose Structure
D-glucose is an aldohexose sugar with the following structure:
- The molecular formula is C₆H₁₂O₆.
- The structure includes an aldehyde group (CHO) at one end and five hydroxyl (OH) groups.

### Step 2: Reaction of D-Glucose with Tollen's Reagent
When D-glucose reacts with Tollen's reagent (Ag(NH₃)₂⁺ in the presence of OH⁻), the aldehyde group (CHO) is oxidized to a carboxylic acid (COOH). The reaction can be summarized as follows:
- The aldehyde group (CHO) is converted to a carboxylate ion (COO⁻).
- The product formed is gluconic acid (C₆H₁₂O₇) in the form of its salt.

**Product A:** The product (A) formed from the reaction of D-glucose with Tollen's reagent is **gluconic acid**.

### Step 3: Reaction of D-Glucose with Bromine Water
Bromine water (Br₂ in water) is a mild oxidizing agent. When D-glucose reacts with bromine water, the aldehyde group (CHO) is again oxidized to a carboxylic acid (COOH). The remaining hydroxymethyl group (CH₂OH) remains unchanged.

**Product B:** The product (B) formed from the reaction of D-glucose with bromine water is also **gluconic acid**.

### Final Answer:
- (A) is **gluconic acid** (from Tollen's reagent).
- (B) is **gluconic acid** (from bromine water).
