Reactions with Hydrocarbons
Definition A hydrocarbon is an organic compound that contains only CARBON and HYDROGEN atoms. We burn many hydrocarbons as FUEL
Combustion Combustion means burning or to burn. Combustion can be either complete or incomplete Incomplete combustion can be very dangerous!
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
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
***carbon monoxide is very dangerous!
Time to look at hydrocarbons and their structure!
