Glucose reacts with excess of phenylhydrazine and forms

Options

A. Glucosazone
B. Glucose phenylhydrazone
C. Glucose oxime
D. Sorbitol

Answer

To solve the question, we need to analyze the reaction between glucose and phenylhydrazine. Here’s a step-by-step breakdown of the process:

### Step 1: Understand the Reactants
- **Glucose**: A simple sugar (monosaccharide) that is an important energy source in living organisms.
- **Phenylhydrazine**: An organic compound used to detect carbonyl compounds (like sugars) through the formation of hydrazones.

### Step 2: Identify the Reaction Type
- When glucose reacts with phenylhydrazine, it undergoes a condensation reaction. This reaction typically involves the formation of a hydrazone.

### Step 3: Reaction Mechanism
1. **Formation of Glucosazone**: When glucose reacts with excess phenylhydrazine, it first forms a phenylhydrazone derivative. However, in the presence of excess phenylhydrazine, glucose can undergo further reaction.
2. **Oxidation and Rearrangement**: The reaction leads to the formation of glucosazone, which is a more stable product formed by the reaction of glucose with phenylhydrazine.

### Step 4: Conclusion
- The final product of the reaction between glucose and excess phenylhydrazine is **Glucosazone**.

### Final Answer
- **Glucose reacts with excess of phenylhydrazine to form Glucosazone.**
