Consider the following reaction Glucose `overset("Reagent")rarr"Mannose"` The above reaction is known as

Options

A. Anomerisation
B. Recemisation
C. Epimerisation
D. Conversion

Answer

To solve the question regarding the conversion of glucose to mannose, we need to identify the type of reaction taking place. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Reactants and Products
- The reactant is glucose, and the product is mannose.
- Both glucose and mannose are monosaccharides (simple sugars).

**Hint:** Look for structural similarities and differences between glucose and mannose.

### Step 2: Understand the Concept of Epimers
- Epimers are a specific type of stereoisomer where two sugars differ in configuration at only one specific carbon atom.
- Glucose and mannose differ at the C2 carbon atom.

**Hint:** Recall the definition of epimers and how they relate to stereochemistry.

### Step 3: Analyze the Reaction Type
- Since glucose and mannose are C2 epimers, the conversion of glucose to mannose involves a change in configuration at the second carbon atom while keeping the rest of the structure the same.
- This type of reaction is specifically called epimerization.

**Hint:** Focus on the carbon atom that changes configuration to determine the reaction type.

### Step 4: Choose the Correct Answer
- The options provided are:
A. Anomerization
B. Racemization
C. Epimerization
D. Conversion
- Since the reaction involves the conversion of glucose to mannose, which are epimers, the correct answer is option C: Epimerization.

**Hint:** Eliminate options that do not fit the definition of the reaction taking place.

### Final Answer
The reaction of glucose converting to mannose is known as **epimerization** (Option C).
