📝 Important Questions for 2027 Exam
Q1: Why does carbon form covalent bonds? Explain with examples.
Answer: Carbon has 4 valence electrons. It needs 4 more electrons to achieve noble gas configuration. Instead of gaining or losing 4 electrons (which requires too much energy), it shares electrons with other atoms forming covalent bonds.
Q2: What are allotropes? Describe the structure of diamond and graphite.
Answer: Allotropes are different structural forms of the same element. Diamond has a tetrahedral structure where each carbon is bonded to 4 others (hardest substance). Graphite has hexagonal layers where each carbon is bonded to 3 others (soft, conducts electricity).

⚡ Quick Revision Tips
- Remember: Carbon = 4 bonds (tetravalent)
- Covalent bonds = share electrons (not transfer)
- CH₄ = Methane, C₂H₆ = Ethane, C₂H₄ = Ethene, C₂H₂ = Ethyne
- Functional groups determine chemical properties
- Soap molecule: hydrophilic head + hydrophobic tail
