Step 1: Understanding the Question:
The question asks for the product formed when glucose, an aldohexose, is treated with a strong oxidizing agent like concentrated nitric acid (conc. ).
Step 3: Detailed Explanation:
1. Nature of Reagent: Concentrated nitric acid is a powerful oxidizing agent.
2. Reaction with Glucose: Glucose contains an aldehyde group ( ) at and a primary alcohol group ( ) at .
3. Oxidation: Conc. is strong enough to oxidize both the aldehyde group and the primary alcohol group to carboxylic acid groups ( ).
4. Product Formation: The resulting dicarboxylic acid is known as Saccharic acid (or glucaric acid). The chemical equation is represented as:
Step 4: Final Answer:
The oxidation of glucose with concentrated nitric acid yields Saccharic Acid, which corresponds to option (B).
