Organic Chemistry

• crude oil is found in rocks which is a finite resource
• crude oil is formed over millions of years from plankton buried in mud
• crude oil is a mixture of hydrocarbons
• hydrocarbons are molecules made up of hydrogen and carbon atoms only
• alkanes have the general formula CnH2n+2
• alkanes are saturated molecules because the carbon atoms are fully bonded to the hydrogen atoms
• Methane is CH4
• Ethane is C2H6
• Propane is C3H8
• Butane is C4H10
