Explain the given reactions with examples:
- Combustion reaction
- Oxidation reaction
- Substitution reaction
Answer:
1. Combustion reaction: Carbon compounds burns in oxygen to produce carbon dioxide along with release of large amount of heat and light.
2. Oxidation reaction: Ethanol is oxidised to ethanoic acid in the presence of alkaline KMn04 (oxidising agent) on heating.
3. Substitution reaction: In the presence of sunlight, chlorine replaces the hydrogen atom of hydrocarbons.
