  1. Alkanes, Alkenes and Cracking

  2. Alkanes Formula • The chemistry of carbon compounds is called organic chemistry. • Members of a particular series will have similar chemical properties. • Main source of alkanes is from crude oil. • They are covalent compounds. • Hydrocarbons general formula for an alkane is CnH2n+2.

  3. Alkenes • The Formula is: CnH2n • Boiling point, melting point and densities increase with larger size molecules. • Insoluble in water. • Burnto produce carbon dioxide and water. • Alkenes are more reactive than alkanes.

  4. Catalysts or heat may be used to crack the alkane chain into smaller ones. • one of the products that is formed when we crack naphtha contains a double bond between two carbon atoms. Cracking
