Alkenes

Alkenes are a type of hydrocarbon, meaning they are made up of carbon and hydrogen atoms. They are characterized by having at least one double bond between two carbon atoms, which gives them more reactive properties compared to alkanes (which only have single bonds). This double bond allows alkenes to participate in chemical reactions such as adding other atoms or groups of atoms across the double bond. Alkenes are found in many natural and industrial processes, including the production of plastics, fuels, and chemicals. Their structure and reactivity make them important building blocks in chemistry.
