  •  The alkanes are hydrocarbons

  • Saturated hydrocarbons: they only contain single bonds

  • General formula: CnH2n+2

  •  The molecular formula of eicosane is C20H42
  • Number of carbons, n = 20, so there are 20 carbons

  • Number of hydrogens, n = 20, so (2×20) + 2 = 42, so there are 42 hydrogen atoms

  •  Cyclohexanes have a ring stucture
