State that the products of cracking include alkanes and alkenes.

In the subtopic Cracking and alkenes, this learning objective focuses on state that the products of cracking include alkanes and alkenes. 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 cracking, alkane, alkene. A useful focus word is cracking, because it keeps the revision tied to the exact organic family, formula, reaction, property, or product being tested. Avoid the mistake of students often state that the products of cracking are only alkenes, forgetting that alkanes are also produced; instead, remember that cracking produces both alkanes and alkenes. Review the definitions and examples of each to reinforce this understanding For exam answers, remember that cracking produces both alkanes and alkenes, and be able to identify their differences 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.
