Carbon and its Compounds

Master covalent bonding, versatile carbon, homologous series, nomenclature, reactions of carbon compounds, soaps and detergents.

Core concepts checklist

Covalent bonds and electron-dot structures
Tetravalency, catenation and carbon allotropes
Saturated and unsaturated hydrocarbons
Functional groups and homologous series
Ethanol, ethanoic acid, soap and detergent action

Formula & fact bank

CH₄ + 2O₂ → CO₂ + 2H₂O
C₂H₄ + H₂ → C₂H₆ (Ni)
CH₃COOH + C₂H₅OH ⇌ CH₃COOC₂H₅ + H₂O
2CH₃COOH + 2Na → 2CH₃COONa + H₂

Diagrams to practise

Draw with pencil, use straight label lines, add arrows and write a precise caption.

  1. 1Electron-dot structures of CH₄ and CO₂
  2. 2Soap micelle
  3. 3Homologous-series functional-group map

CBSE examiner focus

  • Draw all shared electron pairs clearly
  • Distinguish substitution and addition reactions
  • Explain micelles and why soap fails in hard water

Board-style practice

3 marks
