Homologous Series

• All hydrocarbons contain Hydrogen and Carbon
• A homologous series is a group of compounds that have the same functional group and the same general formula
• The general formula for alkanes is

  $CnH2n+$$2$
• The general formula for alkenes is

  $CnH2n$
• All hydrocarbons contain carbon and hydrogen atoms, but they can be arranged in different ways.
• A homologous series is a group of compounds that have the same functional group and the same general formula.
• Unsaturated molecules a tested by adding bromine water and observing a colour change.
• The general formula for cycloalkanes is CnH2n+2
• The prefixes for hydrocarbons are, Meth, Eth, Prop, But, Pent, Hex, Hept, Oct.
• An isomer is a molecule with the same molecular formula but a different structural formula.
• An unsaturated molecule is a molecule with at least one double bond.
• Addition of water to an alkene is known as hydration.
• The addition of hydrogen to an alkene is known as hydrogenation.
