Combustion of Carbon Compounds
Combustion of Carbon Compounds
Combustion:
The carbon compounds (including its allotropic forms) burn in oxygen to give carbon dioxide and water vapors. Heat and light are also released during this process. This reaction is called as combustion.
Further, once carbon and its compounds ignite, they keep burning without the requirement of additional energy. That’s why these compounds are used as fuels. Saturated hydrocarbons give a clean blue flame due to their complete combustion whereas, unsaturated hydrocarbons have a yellow flame with lots of black smoke as they do not undergo complete combustion.
The burning of unsaturated hydrocarbons always results in the deposition of soot [a black substance]. However, in the limited supply of air, even saturated hydrocarbons undergo incomplete combustion and give a sooty flame.
