(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 problem, we need to determine the products formed when D-glucose is treated with Tollen's reagent and bromine water.

### Step 1: Understand the structure of D-glucose
D-glucose is an aldohexose sugar with the molecular formula C₆H₁₂O₆. It has a six-membered ring structure (pyranose form) in its cyclic form.

### Step 2: Reaction of D-glucose with Tollen's reagent
Tollen's reagent (Ag(NH₃)₂⁺) is a mild oxidizing agent that oxidizes aldehydes to carboxylic acids. D-glucose has an aldehyde group at the first carbon atom. When D-glucose is treated with Tollen's reagent, the aldehyde group is oxidized to a carboxylic acid.

- **Reaction**:
\[ \text{D-glucose} \xrightarrow{\text{Tollen's reagent}} \text{Gluconic acid} \]

The product formed (A) is gluconic acid (C₆H₁₂O₇).

### Step 3: Reaction of D-glucose with bromine water
Bromine water (Br₂ in water) is another oxidizing agent that can oxidize the aldehyde group of D-glucose to a carboxylic acid.

- **Reaction**:
\[ \text{D-glucose} \xrightarrow{\text{Bromine water}} \text{Gluconic acid} \]

The product formed (B) is also gluconic acid (C₆H₁₂O₇).

### Conclusion
Both reactions yield the same product, which is gluconic acid. Therefore, we conclude that:

- (A) = Gluconic acid
- (B) = Gluconic acid

### Final Answer
(A) and (B) are both gluconic acid.
