What is the general formula for the homologous series of alkenes?

The general formula for the homologous series of alkenes is CnH2n, where n represents the number of carbon atoms in the molecule.

This question tests the student's understanding of the structural characteristics of alkenes. Knowing the general formula is fundamental for identifying and differentiating alkenes from other hydrocarbons. This response is aligned to Structure and formulae of alkenes because it explains state the general formula for the homologous series of alkenes as CnH2n using the correct AQA GCSE Chemistry organic context. 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.
