Aspirin is also known as:

Show Hint

Aspirin is chemically known as acetylsalicylic acid, which is derived from salicylic acid. It is made by adding an acetyl group (–COCH₃) to the hydroxyl group of salicylic acid. This modification helps reduce the irritation caused by pure salicylic acid and makes aspirin a widely used pain reliever and anti-inflammatory drug.

  • Salicylic acid
  • Ethyl Salicylic acid
  • Methyl Salicylic acid
  • Acetyl Salicylic acid
Show Solution

The Correct Option is D

Solution and Explanation

Aspirin, chemically known as Acetyl Salicylic acid, is a widely used medication for its analgesic, anti-inflammatory, and fever-reducing effects. Its structure features a salicylate component with an attached acetyl group, distinguishing it from other salicylic acid variants.

Key terms are defined as follows:

  • Salicylic Acid: The foundational compound, characterized by a hydroxyl group on a benzene ring, which serves as the basis for aspirin synthesis.
  • Ethyl Salicylic Acid: A theoretical variant wherein the hydroxyl group of salicylic acid is substituted with an ethoxy group; this is not aspirin.
  • Methyl Salicylic Acid: Another theoretical variant where the hydroxyl group is replaced by a methoxy group; this is also not aspirin.
  • Acetyl Salicylic Acid: The accurate designation for aspirin, formed by attaching an acetyl group to the hydroxyl group of salicylic acid.

Aspirin, or Acetyl Salicylic acid, derives its IUPAC nomenclature primarily from the crucial addition of the acetyl group.
