GCSE Chemistry - Addition Reactions of Alkenes #55

The video tutorial explains the reactions of alkenes, which are unsaturated hydrocarbons with carbon-carbon double bonds. These double bonds allow alkenes to undergo addition reactions with hydrogen, water, and halogens. The video covers hydrogenation, where alkenes react with hydrogen to form alkanes, hydration, where alkenes react with water to form alcohols like ethanol, and halogenation, where alkenes react with halogens such as bromine. The tutorial also discusses the separation of reaction products using fractional distillation and the use of bromine as a test to distinguish alkenes from alkanes.

How is ethanol produced from the reaction of ethene with water?

What is the method used to separate ethanol from unreacted ethene and water?

How do alkenes react with halogens, and what is the significance of this reaction?
