Key Topics to Revise

1

Carbon - Basic Properties and Bonding

  • Carbon belongs to Group 14 (IV A) with atomic number 6
  • Electronic configuration: 1s² 2s² 2p²
  • Cannot form C⁴⁺ or C⁴⁻ ions easily due to energy requirements
2

Hybridization

  • sp³ hybridization: One s + three p orbitals → four equivalent sp³ orbitals
  • sp² hybridization: One s + two p orbitals → three sp² orbitals + one unhybridized p
  • sp hybridization: One s + one p orbital → two sp orbitals + two unhybridized p
3

Allotropes of Carbon

  • Amorphous forms: Coal, coke, charcoal, lamp black, gas carbon
  • Crystalline forms: Diamond, graphite, buckminsterfullerene
  • Diamond: sp³ hybridization, 3D network, hardest material
4

Hydrocarbons

  • Compounds containing only carbon and hydrogen
  • Alkanes: CₙH₂ₙ₊₂ (saturated, single bonds only)
  • Alkenes: CₙH₂ₙ (unsaturated, at least one double bond)
