). The reaction with bromine water is a standard test for unsaturation: the orange-brown liquid turns . Reaction with Hydrogen (Hydrogenation): Adding H2cap H sub 2

Reacting an alkene with water (steam) in the presence of a phosphoric acid catalyst produces an alcohol (e.g., ethene becomes ethanol).

is a widely used chemistry worksheet focused on the fundamental properties and reactions of alkenes . For students preparing for AQA, Edexcel, or OCR exams, mastering this content is essential for understanding organic chemistry and the behavior of unsaturated hydrocarbons. Understanding Alkenes (GCSE 1232) chemsheets 1232 answers

). This double bond is their functional group and is responsible for their high chemical reactivity compared to alkanes. The general formula for alkenes is CnH2ncap C sub n cap H sub 2 n end-sub Key Examples: Common alkenes include ethene ( C2H4cap C sub 2 cap H sub 4 ), propene ( C3H6cap C sub 3 cap H sub 6 ), and butene ( C4H8cap C sub 4 cap H sub 8

Always remember that the bromine water test distinguishes between alkanes (no color change) and alkenes (decolorizes). is a widely used chemistry worksheet focused on

The worksheet emphasizes the various that alkenes undergo. In these reactions, the double bond breaks to form a single bond, allowing new atoms to join the carbon atoms.

While alkenes can burn, they often undergo incomplete combustion , resulting in a smoky flame due to unburnt carbon particles. Key Concepts for Exam Success This double bond is their functional group and

Alkenes are the monomers used to create addition polymers like poly(ethene). This involves thousands of alkene molecules joining together as the double bonds open up.

For more comprehensive practice, you can find similar resources on the official Chemsheets website or revision guides on Physics & Maths Tutor .

Alkenes are a homologous series of that contain at least one carbon-to-carbon double bond (
