Incomplete Combustion of Alkenes

Due to the high percentage of carbon in alkenes, they normally udergo incomplete combustion to give carbon monoxide with yellow smoky flames. Remember from combustion of alkanes that incomplete combustion is as a result of limiting oxygen. Note as was stated for alkanes, combustion is burning in the presence of oxygen.
