State that complete combustion of a hydrocarbon produces carbon dioxide and water.

In the subtopic Properties and combustion of hydrocarbons, this learning objective focuses on state that complete combustion of a hydrocarbon produces carbon dioxide and water. It sits within Carbon compounds as fuels and feedstock for AQA GCSE Chemistry 8462 Unit 4.7 Organic chemistry, so the explanation must stay anchored to organic chemistry rather than becoming a generic carbon-compounds fact. Approved keywords to use include combustion, complete combustion, carbon dioxide, water, hydrocarbon. Complete combustion. means the reaction of a hydrocarbon with oxygen that produces carbon dioxide and water Avoid the mistake of students often state that complete combustion of hydrocarbons produces carbon monoxide instead of carbon dioxide; instead, remember that complete combustion occurs when there is enough oxygen, resulting in carbon dioxide and water as products For exam answers, remember that complete combustion of hydrocarbons produces carbon dioxide and water. Write down the general equation for this reaction to help recall it during the exam Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.
