Title: Incomplete Combustion
Post by: Shark 774 on May 25, 2011, 08:34:16 pm

What causes incomplete combustion? We did it in class and cyclohexene didn't completely combust and I know incomplete combustion can be caused by a lack of oxygen, yet it a classroom full of oxygen I wouldn't expect that to be the reason..

Incomplete combustion occurs due to a lack of oxygen. I'm not sure what happened for you, but

the products of incomplete combustion are some of

CO2
CO
C (soot)


and H20

it was probably because you had your bunsen burner on a closed flame so less oxygen would be getting through

there may be plentiful supply of oxygen, but the flame isnt hot enough to react the reactants together
