It also covers addition reactions, particularly hydrogenation, which converts alkenes to alkanes using a platinum catalyst, and hydration reactions involving water and alkenes. Additionally, the text points out that benzene is resistant to addition reactions under mild conditions but can react under high temperatures and pressure.
