Reactions of Alkenes and Alkanes

The video tutorial covers three major reactions involving alkenes and alkanes: hydrohalogenation, hydrogenation, and halogenation. Hydrohalogenation involves adding a hydrogen and a halogen to an alkene, converting a double bond into a single bond. Hydrogenation is similar but only involves adding hydrogen atoms. Halogenation involves adding halogen elements to an alkene, also converting double bonds into single bonds. Each reaction is an addition reaction, where elements are added to the original structure, transforming its chemical bonds.
