Options

A. Dehydration
B. oxidation
C. Reduction
D. Sulphonation

Answer

To solve the question regarding the reaction of concentrated sulfuric acid with carbohydrates (specifically C12H22O11, which is cane sugar), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**:
The reaction in question involves concentrated sulfuric acid (H2SO4) reacting with the carbohydrate C12H22O11.

2. **Understand the Nature of the Reaction**:
Concentrated sulfuric acid acts as a dehydrating agent. This means it removes water (H2O) from the carbohydrate.

3. **Write the Chemical Equation**:
The balanced chemical equation for the dehydration of cane sugar (C12H22O11) by concentrated sulfuric acid can be represented as:
\[ C_{12}H_{22}O_{11} \xrightarrow{H_2SO_4} C_{12}H_{22} + 11H_2O \]
Here, the sulfuric acid removes water from the sugar molecule.

4. **Classify the Reaction**:
Since the reaction involves the removal of water, it is classified as a dehydration reaction. Dehydration reactions involve the loss of water from the reactants.

5. **Conclusion**:
Therefore, the reaction of concentrated sulfuric acid with carbohydrates, specifically C12H22O11, is an example of a dehydration reaction.

### Final Answer:
The reaction of concentrated sulfuric acid with carbohydrates (C12H22O11) is an example of **dehydration**.
