Which one among the following is an example of oxidation reaction?

Correct option is C

The correct answer is (c) Rusting of iron.
Explanation: Rusting of iron is an example of an oxidation reaction. In this process, iron reacts with oxygen in the presence of water or moisture to form iron oxide, commonly known as rust. During oxidation, iron loses electrons to oxygen, resulting in a chemical change where iron is transformed into iron oxide (Fe₂O₃). This process exemplifies oxidation because iron undergoes a reaction where it combines with oxygen, losing electrons in the process.
Information Booster:
● Oxidation Reaction: Involves the loss of electrons or the gain of oxygen by a substance. ● Rusting: A classic example where iron oxidizes to form iron oxide in moist air. ● Redox Reactions: Oxidation reactions are often coupled with reduction reactions (where another substance gains electrons). ● Corrosion: Rusting is a form of corrosion, which is an oxidation process affecting metals.
Additional Knowledge:
· Option (a) - Freezing of water: A physical change, not a chemical reaction or oxidation.
· Option (b) - Dissolving sugar in water: A physical change where sugar disperses in water without any chemical reaction.
· Option (d) - Boiling of petrol: Another physical change, involving a phase change from liquid to gas without oxidation.
