Question

alkenes methods preparation and definition ​

Answer 1

Answer:

Definition : Alkenes are a class of hydrocarbons (e.g., containing only carbon and hydrogen) unsaturated compounds with at least one carbon-to-carbon double bond.

Preparations : Alkenes are generally prepared through β elimination reactions, in which two atoms on adjacent carbon atoms are removed, resulting in the formation of a double bond. Preparations include the dehydration of alcohols, the dehydrohalogenation of alkyl halides, and the dehalogenation of alkanes.
