Question

In the following reaction of (D)-Glucose, a product P is formed.

Among the following compounds, the one which will give the same product (P) under identical reaction conditions is 
 

• A. A
• B. B
• C. C
• D. D

Hint:

The oxidation of glucose with bromine in water results in gluconic acid, and similar compounds with similar functional groups will undergo the same transformation.

Answer 1

The Correct Option is D

Step 1: Understanding the reaction.
This reaction involves oxidation of glucose in the presence of bromine water (Br$_2$ / H$_2$O) followed by treatment with hydrogen peroxide and ferric sulfate. The first step oxidizes the aldehyde group to a carboxylic acid, and the second step converts the cyclic structure into an open-chain form. The product formed from (D)-Glucose in these conditions is gluconic acid.
Step 2: Analyzing the compounds.
Among the compounds listed, only compound (B) is the one that, under identical conditions, will undergo the same oxidation and conversion process to form gluconic acid. The other structures differ in terms of hydroxyl and aldehyde positions.
Step 3: Conclusion.
Thus, the correct answer is (B).
