**2. Properties of Carbon (10 minutes)**
- Discuss the unique properties of carbon, including its tetravalency and ability to form stable covalent bonds.
- Illustrate the concept of catenation (self-linking) with examples.
**3. Allotropes of Carbon (10 minutes)**
- Explain what allotropes are and introduce diamond, graphite, and fullerenes.
- Show samples, if available, and engage students with questions about the different uses of each allotrope.
- Use molecular models to demonstrate the structures of these allotropes.
**4. Introduction to Hydrocarbons (10 minutes)**
- Define hydrocarbons and explain their significance.
- Classify them into alkanes, alkenes, and alkynes with general formulas.
- Discuss the basic structure and naming conventions for each type.
**5. Chemical Reactions Involving Hydrocarbons (15 minutes)**
- Describe and provide examples of combustion, substitution, and addition reactions.
- Use simple chemical equations to explain each reaction type.
- Demonstrate one of the reactions through a simple and safe classroom experiment, if possible.
**6. Practice Activity (10 minutes)**
- Hand out worksheets containing questions about the classification and reactions of hydrocarbons.
- Allow students to work in pairs to solve problems and discuss answers.
**7. Conclusion and Q&A (5 minutes)**
- Summarize the lesson key points.
- Encourage students to ask questions and clarify any doubts.
- Provide a brief overview of the next lesson.
