Question

Which parts of acetylsalicylic acid are rigid?

A) The carboxyl group
B) The acetyl group
C) The aromatic ring
D) The hydroxyl group

Answer 1

The aromatic ring and the acetyl group in acetylsalicylic acid are rigid.

Step-by-step explanation:

The parts of acetylsalicylic acid that are rigid are:

• The aromatic ring: The aromatic ring in acetylsalicylic acid is rigid because it consists of a planar structure formed by alternating double bonds.
• The acetyl group: The acetyl group in acetylsalicylic acid is also rigid because it contains a carbonyl group (C=O) which has a fixed arrangement of atoms.
