Glycerol reacts with Conc. `HNO_(3)` and Conc. `H_(2)SO_(4)` to form

Options

A. Glycerol mononitrate
B. Glycerol dinitrate
C. Glycerol trinitrate
D. Acrolein

Explanation

To determine the products formed when glycerol reacts with concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4), we can follow these steps:

### Step 1: Understand the Reactants
Glycerol, also known as glycerin, has the chemical formula C3H8O3. It contains three hydroxyl (–OH) groups, which makes it a triol.

### Step 2: Identify the Reaction Conditions
The reaction involves concentrated nitric acid and concentrated sulfuric acid. The sulfuric acid acts as a dehydrating agent, facilitating the nitration process.

### Step 3: Nitration of Glycerol
In the presence of concentrated HNO3 and H2SO4, glycerol undergoes nitration. This process involves the substitution of hydroxyl groups (–OH) with nitro groups (–NO2).

### Step 4: Determine the Possible Products
Since glycerol has three hydroxyl groups, it can be nitrated at each of these positions. The possible products include:
- Mononitrate glycerol (one –NO2 group)
- Dinitrate glycerol (two –NO2 groups)
- Trinitrate glycerol (three –NO2 groups)

### Step 5: Identify the Major Product
The major product of this reaction is trinitrate glycerol, commonly known as nitroglycerin. This compound is highly explosive and is used in explosives and as a vasodilator in medicine.

### Final Answer
Glycerol reacts with concentrated HNO3 and concentrated H2SO4 to form trinitrate glycerol (nitroglycerin).
