General Formulas:

Alkanes

Formula: CₙH₂ₙ₊₂

Bonds: All single bonds

Examples: Methane, Ethane, Propane

Alkenes

Formula: CₙH₂ₙ

Bonds: One C=C double bond

Examples: Ethene, Propene, Butene

Alkynes

Formula: CₙH₂ₙ₋₂

Bonds: One C≡C triple bond

Examples: Ethyne, Propyne, Butyne

Cycloalkanes

Formula: CₙH₂ₙ

Structure: Ring of carbon atoms

Examples: Cyclopropane, Cyclohexane

Properties:

  • Boiling point: Increases with chain length and branching
  • Solubility: Generally insoluble in water, soluble in nonpolar solvents
  • Reactivity: Alkanes < Alkenes < Alkynes
  • Density: Generally less dense than water
  • Combustion: All hydrocarbons burn to produce CO₂ and H₂O

Common Uses:

Fuels: Natural gas (methane), gasoline (C₅-C₈), diesel (C₁₀-C₂₀)

Solvents: Hexane, cyclohexane, toluene

Raw materials: Ethylene (plastics), acetylene (welding), benzene (chemicals)

Lubricants: Long-chain alkanes for motor oils
