To determine the functional groups present in aspirin (acetylsalicylic acid), let’s identify the components of its molecular structure.

Step 1: Identify the Structure of Aspirin

Aspirin has the chemical formula C₉H₈O₄. Its structure consists of:

• An acetyl group (-COCH₃)
• A salicylate group, which includes a carboxylic acid (-COOH) and a phenolic hydroxyl group (-OH).

Step 2: Analyze Functional Groups

1. Carboxylic Acid: Aspirin contains a carboxylic acid group (-COOH).
2. Ester: The acetyl group bonded to the salicylate structure forms an ester bond.
3. Alcohol: The phenolic -OH group qualifies as an alcohol functional group.
4. No Ketone or Aldehyde: The molecule does not contain a ketone (R-CO-R') or aldehyde (R-CHO) functional group.
5. No Amide or Amine: Aspirin does not have an amide (R-CONH₂) or amine (R-NH₂) functional group.

Step 3: Confirm Findings

The functional groups can be summarized as follows:

• Carboxylic Acid: Yes
• Ester: Yes
• Alcohol: Yes
• Ketone: No
• Aldehyde: No
• Amide: No
• Amine: No

Final Answer

The functional groups found in aspirin are:

1. Carboxylic acid
2. Ester
3. Alcohol
