The reaction of concentrated sulphuric acid with carbohydrates `(C_(12)H_(22)O_(11)` is an example of

Options

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

Answer

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

### Step 1: Understand the Reaction
The reaction in question involves concentrated sulfuric acid (H₂SO₄) and a carbohydrate, specifically sucrose (C₁₂H₂₂O₁₁).

### Step 2: Identify the Nature of Sulfuric Acid
Concentrated sulfuric acid is known to be a strong dehydrating agent. This means it has the ability to remove water (H₂O) from substances.

### Step 3: Analyze the Reaction with Carbohydrates
When concentrated sulfuric acid is added to carbohydrates, it removes water molecules from the carbohydrate structure. In the case of sucrose, the reaction leads to the formation of carbon and water is lost.

### Step 4: Define Dehydration
Dehydration is the process of removing water from a substance. In this context, the reaction of concentrated sulfuric acid with sucrose results in the removal of water, thus classifying it as a dehydration reaction.

### Step 5: Conclusion
Based on the analysis, we can conclude that the reaction of concentrated sulfuric acid with carbohydrates (C₁₂H₂₂O₁₁) is an example of dehydration.

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