Reactions of Alkenes |10th Chemistry |Chapter-22

Welcome back to the channel! In today’s lesson, we continue our deep dive into Chapter 22: Hydrocarbons. We will explore the important chemical reactions of alkenes, focusing on why alkenes are so reactive due to their carbon-carbon double bond.  Whether you are studying for your school exams or brushing up on your chemistry fundamentals, this step-by-step breakdown makes organic chemistry easy to understand! In this video, we cover: Addition of Hydrogen (Catalytic Hydrogenation): How ethene reacts with hydrogen in the presence of a nickel catalyst to form alkanes.  Addition of Halogens: How halogens like bromine react to give alkyl dihalides and how this serves as a test for unsaturation.  Oxidation with Water and oxygen Using cold, dilute alkaline potassium permanganate to produce ethylene glycol (ethane-1,2-diol).  Addition of Hydrogen Halides: The hydrohalogenation process converting ethene to bromoethane.  Addition of Water (Hydration): How alkenes react with steam in the presence of sulphuric acid at 300 °C to form alcohols like butan-2-ol.
