Introduction to Alkenes and Cracking of Alkanes

This video provides an overview of alkenes, a type of hydrocarbon that contains a double carbon-carbon bond in their molecules. The video covers the structure and formulas of several alkenes, including ethene, propane, butene, and pentene, and explains how these molecules can be obtained by cracking larger alkanes. The video also discusses the properties of alkenes, including their unsaturation due to the lack of hydrogen atoms, their combustion reactions, and their reactivity with other elements through addition reactions. The process of cracking, both steam and catalytic, is also explained and demonstrated through a laboratory experiment. Additionally, the video explores how alkanes are broken down into smaller and more useful alkenes through cracking.
