Glycerol reacts with potassium bisulphate to produce

Options

A. Allyl iodide
B. Allyl sulphate
C. Acraldehyde
D. Glycerol trisulphate

Explanation

To determine the product of the reaction between glycerol and potassium bisulfate, we can follow these steps:

### Step 1: Understand the Reactants
Glycerol is a triol with the chemical formula C3H8O3, which can be represented as:
\[ \text{HO-CH}_2\text{-CHOH-CH}_2\text{-OH} \]

Potassium bisulfate (KHSO4) is a dehydrating agent.

### Step 2: Reaction Mechanism
When glycerol is heated with potassium bisulfate, it undergoes dehydration. The bisulfate ion (HSO4-) removes a water molecule from glycerol, leading to the formation of an unsaturated compound.

### Step 3: Formation of the Product
The dehydration of glycerol can lead to the formation of an allyl group, which is characterized by the structure:
\[ \text{CH}_2=CH-CH}_2\text{-OH} \]
This structure can further rearrange to form acrolein (acryldehyde), which has the formula:
\[ \text{CH}_2=CH-CHO \]

### Step 4: Identify the Correct Product
From the options provided:
1. Allyl iodide
2. Allyl sulfate
3. Acryldehyde
4. Glycerol trisulfate

The product formed from the reaction of glycerol with potassium bisulfate is **acryldehyde** (option 3).

### Final Answer
The product of the reaction between glycerol and potassium bisulfate is **acryldehyde**.
