The charging of sugar , when treated with conc. `H_(2)SO_(4)`, is due to

Options

A. Oxidation
B. Reduction
C. Dehydration
D. Hydrolysis

Explanation

To solve the question regarding the charging of sugar when treated with concentrated H₂SO₄, we can follow these steps:

### Step 1: Understand the Reaction
When sugar (which is a carbohydrate) is treated with concentrated sulfuric acid (H₂SO₄), a dehydration reaction occurs. This means that the sulfuric acid removes water (H₂O) from the sugar molecule.

**Hint:** Consider what happens to the molecular structure of sugar when water is removed.

### Step 2: Identify the Products
As a result of dehydration, the sugar breaks down into carbon (C) and other byproducts, which may include carbon dioxide (CO₂) and other compounds depending on the conditions. The carbon produced is often in the form of black char.

**Hint:** Think about the elements that make up sugar and what remains after water is removed.

### Step 3: Observe the Color Change
The black char produced from the carbon gives the sugar a darkened appearance, which is often referred to as "charring." This is a visual indication of the reaction taking place.

**Hint:** Pay attention to the visual changes that occur during chemical reactions.

### Step 4: Conclude the Reason for Charring
The charring of sugar when treated with concentrated H₂SO₄ is primarily due to the dehydration of the sugar, leading to the formation of carbon and other products.

**Hint:** Relate the chemical changes to the physical appearance of the substance.

### Final Answer
The charring of sugar when treated with concentrated H₂SO₄ is due to the dehydration of the sugar, resulting in the formation of carbon and other byproducts.
