Key Topics to Revise

1

Classification and General Introduction

  • Hydrocarbons contain only carbon and hydrogen atoms
  • Three main categories: Saturated (alkanes), Unsaturated (alkenes, alkynes), and Aromatic
  • Saturated hydrocarbons have only single bonds (C-C and C-H)
2

Alkanes - Structure, Nomenclature, and Isomerism

  • Saturated hydrocarbons with sp³ hybridized carbon atoms
  • Tetrahedral geometry with bond angles of 109.5°
  • C-C bond length: 154 pm, C-H bond length: 112 pm
3

Alkanes - Preparation and Reactions

  • Preparation methods: Hydrogenation of alkenes/alkynes, Reduction of alkyl halides, Wurtz reaction, Decarboxylation
  • Chemical properties: Generally unreactive (called paraffins)
  • Substitution reactions: Halogenation by free radical mechanism
4

Alkenes - Structure, Nomenclature, and Isomerism

  • Contain C=C double bond with sp² hybridized carbons
  • Double bond consists of one σ bond (397 kJ/mol) and one π bond (284 kJ/mol)
  • C=C bond length: 134 pm (shorter than C-C single bond)
