Question

Which reaction best represents the complete combustion of ethene?
a.c2h4 + hcl → c2h5cl
b.c2h4 + cl2 → c2h4cl2
c.c2h4 + 3 o2 → 2 co2 + 2 h2o
d.c2h4 + h2o → c2h5oh?

Answer 1

Combustion is when a hydrocarbon (a chemical with carbon and hydrogen) react with oxygen to produce carbon dioxide and water. Since C is the only one with oxygen as a reactant and with CO2 and H2O products, the answer must be C.

Answer 2

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O reaction best represents the complete combustion of ethene.

What is combustion reaction?

Combustion reaction is those reaction in which hydrocarbons are present as fuel which gets oxidized in the presence of oxygen, which present as oxidant for the formation of water molecule and carbon dioxide gas.

From the given reactions, only reaction C₂H₄ + 3O₂ → 2CO₂ + 2H₂O will show the combustion reaction because in this reaction formation of H₂O & CO₂ takes place as the result of the oxidation of ethene.

Hence, option (c) is correct.
