Why does complete combustion of carbon and its compounds give cleaner energy?

Answer and explanation

Correct answer: Because in sufficient oxygen mainly carbon dioxide and water form

Complete combustion occurs when a fuel receives sufficient oxygen. Carbon is then oxidised mainly to carbon dioxide, while hydrogen in the compound forms water, and substantial heat is released. Compared with incomplete combustion, this process produces much less soot and carbon monoxide, a poisonous gas. Carbon dioxide is still a greenhouse gas, so “cleaner” means fewer harmful combustion products, not zero pollution. Option A is correct.
