Solution

The correct option is B Carbon dioxide is produced
Ethene burns in air with a sooty flame producing a large amount of energy. Generation of sooty flame is because of incomplete combustion of ethene.

However, if the supply of air is in excess, it burns with a pale blue flame to produce carbon dioxide, water and a large amount of heat.

C2H4(g)+3O2(g)  2CO2(g)+2H2O(g)+Heat
