Combustion of alkane (Petrol) causes pollution how ?

Answer»

Solution :Octane is a component of PETROL, complete and INCOMPLETE combustion of petrol is occurred according to following reaction :
`C_(8)H_(18) + (17)/(2)O_(2) overset("Incomplete combustion")rarr 8CO + 9H_(2)O`
`C_(8)H_(18) + (25)/(2)O_(2) overset("complete combustion")rarr 8CO_(2) + 9H_(2)O`
CO is poisonous and can form complex with blood. In vechicles, on complete combustion of petrol gives CO and `CO_(2)` which causes pollution.
