Options

A. Muta rotation
B. Inversion
C. Pyrolysis
D. None of these

Explanation

To solve the question regarding the hydrolysis of sucrose into glucose and fructose, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sucrose**:
- Sucrose is a disaccharide composed of glucose and fructose. Its chemical formula is C₁₂H₂₂O₁₁.

2. **Hydrolysis Reaction**:
- Hydrolysis is the chemical process where water is used to break down a compound. In this case, sucrose reacts with water to form D-glucose and D-fructose.
- The reaction can be represented as:
\[ \text{C}_{12}\text{H}_{22}\text{O}_{11} + \text{H}_2\text{O} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 \, (\text{D-glucose}) + \text{C}_6\text{H}_{12}\text{O}_6 \, (\text{D-fructose}) \]

3. **Optical Rotation**:
- Optical rotation is a property of chiral compounds that indicates the degree to which they rotate plane-polarized light.
- Sucrose has a specific rotation of +66.5 degrees, D-glucose has +52.5 degrees, and D-fructose has -92.4 degrees.

4. **Calculating Net Specific Rotation**:
- The net specific rotation after hydrolysis can be calculated using the formula:
\[ \text{Net rotation} = \text{Rotation of glucose} + \text{Rotation of fructose} \]
- Substituting the values:
\[ \text{Net rotation} = +52.5 - 92.4 = -39.9 \text{ degrees} \]

5. **Determining the Type of Reaction**:
- Since the specific rotation changes from a positive value (sucrose) to a negative value (after hydrolysis), this process is referred to as "inversion."
- Therefore, the hydrolysis of sucrose into glucose and fructose is known as "inversion."

### Final Answer:
The hydrolysis of sucrose into (+) glucose and (-) fructose is known as **inversion**.
