Question

Select the odd pair:

Options

• Ozone - Oxidizing bleach

• Petrol - Oxidizing bleach

• Acetone - Reducing bleach

• Ammonia - Reducing bleach

Answer 1

Petrol - Oxidizing bleach

Explanation:

This pair is the odd one out because petrol is an organic solvent, not a bleach. While ozone acts as an oxidising agent and ammonia works as a reducing agent, petrol does not perform any chemical bleaching action. Instead, it is used in dry cleaning solely to dissolve oil, grease, and wax stains.
