1 Reactions with Hydrocarbons

2 Definition  A hydrocarbon is an organic compound that contains only CARBON and HYDROGEN atoms.  We burn many hydrocarbons as FUEL

3 Examples

4 Examples

5 Combustion  Combustion means burning or to burn.  Combustion can be either complete or incomplete  Incomplete combustion can be very dangerous!

6 Complete Combustion  When a hydrocarbon is burned with lots of oxygen  Exothermic  Equation: Hydrocarbon + LOTS of  carbon + water oxygen dioxide oxygen dioxide Ex: CH 4 + 2O 2  CO 2 + 2H 2 O

7 Incomplete Combustion  A hydrocarbon is burned with NOT ENOUGH oxygen  Exothermic  Equation: Hydrocarbon + little  carbon + water + carbon + carbon oxygen dioxide (soot) monoxide oxygen dioxide (soot) monoxide Ex: 4CH 4 + 6O 2  CO 2 + 8H 2 O + C + 2CO

8  ***carbon monoxide is very dangerous!

9 Time to look at hydrocarbons and their structure!
