Acetylation of salicylic acid produces

Options

A. Adipic acid
B. Picric acid
C. Glutaric acid
D. Aspirin

Answer

To solve the question regarding the acetylation of salicylic acid, we will follow these steps:

### Step 1: Understand the structure of Salicylic Acid
Salicylic acid has the following structure:
- It contains a carboxylic acid group (-COOH) and a hydroxyl group (-OH) on a benzene ring.

### Step 2: Define Acetylation
Acetylation is a chemical reaction where an acetyl group (CH3C(=O)-) is introduced into a compound, replacing a hydrogen atom.

### Step 3: Identify the Acetyl Group
The acetyl group is represented as CH3C(=O)-. This group will replace one of the hydrogen atoms in salicylic acid.

### Step 4: Reaction with Acetic Anhydride
In the acetylation process, salicylic acid reacts with acetic anhydride (CH3C(=O)O) to form acetylsalicylic acid. The reaction can be summarized as follows:
- Salicylic Acid + Acetic Anhydride → Acetylsalicylic Acid + Acetic Acid

### Step 5: Write the Chemical Equation
The chemical equation for the reaction can be written as:
\[ \text{C}_7\text{H}_6\text{O}_3 + \text{(CH}_3\text{CO)}_2\text{O} \rightarrow \text{C}_9\text{H}_8\text{O}_4 + \text{CH}_3\text{COOH} \]
Where:
- C7H6O3 is salicylic acid,
- (CH3CO)2O is acetic anhydride,
- C9H8O4 is acetylsalicylic acid (commonly known as Aspirin),
- CH3COOH is acetic acid.

### Step 6: Conclusion
The product of the acetylation of salicylic acid is acetylsalicylic acid.

### Final Answer
Acetylation of salicylic acid produces acetylsalicylic acid (commonly known as Aspirin).
