Propene, also known as propylene, is an unsaturated organic compound hacving the chemical formula C3H6. It has one double bond and is the second simplest member of the alkene class of hydrocarbons, and is also second in natural abundance.
When combusted with oxygen, hydrocarbons give the products carbon dioxide and water, as illustrated in the structural formula below:
2CH3CH=CH2 + 9O2 -----> 6CO2 + 6H2O
Propene resembles other alkenes in that it undergoes addition reactions very easily at room temperature. The relative weakness of the double bond explains it's tendency to react with substances that can achieve this transformation.
