D-Glucose upon treatment with bromine-water gives

Options

A.
B.
C.
D.

Explanation

To solve the question, "D-Glucose upon treatment with bromine-water gives," we can follow these steps:

### Step 1: Understand the structure of D-Glucose
D-Glucose is an aldohexose, meaning it has an aldehyde functional group (-CHO) and six carbon atoms. The molecular formula for D-Glucose is C6H12O6.

### Step 2: Identify the reaction with bromine-water
When D-Glucose is treated with bromine-water, a mild oxidizing agent, the aldehyde group (-CHO) in D-Glucose is oxidized to a carboxylic acid group (-COOH).

### Step 3: Write the product of the reaction
The oxidation of D-Glucose results in the formation of D-gluconic acid. The structure of D-gluconic acid retains the six carbon atoms but now has a carboxylic acid group at one end.

### Step 4: Conclusion
Thus, the final product of the reaction of D-Glucose with bromine-water is D-gluconic acid.

### Final Answer
D-Glucose upon treatment with bromine-water gives D-gluconic acid.
