Описание: Organic Reactions of Alkenes | Addition Reactions, Markovnikov Rule, Stereochemistry & Mechanisms

In this comprehensive Organic Chemistry lecture, we explore the reactions of alkenes, with a major emphasis on electrophilic addition reactions that convert sp²-hybridized carbons into sp³-hybridized carbons, resulting in the formation of saturated σ (sigma) bonds.

The video begins with a conceptual overview of why alkenes are reactive, focusing on the electron-rich π bond and how it participates in addition reactions. We then systematically cover the most important alkene addition reactions encountered in Organic Chemistry I and II.

Reactions Covered

✔️ Hydrohalogenation (addition of HCl and HBr)
✔️ Markovnikov’s Rule and regioselectivity
✔️ Carbocation intermediates and rearrangements to more stable carbocations
✔️ Reaction mechanisms and second-order kinetics (e.g., hydrohalogenation)
✔️ Halogenation (Br₂, Cl₂) and anti-addition
✔️ Halohydrin formation (X₂/H₂O)
✔️ Acid-catalyzed hydration of alkenes
✔️ Hydroboration–oxidation (anti-Markovnikov hydration, syn addition)
✔️ Catalytic hydrogenation (syn addition)

Key Concepts Explained

🔹 Conversion of π bonds to σ bonds
🔹 Syn vs anti addition and stereochemical outcomes
🔹 Regioselectivity vs stereoselectivity
🔹 Carbocation stability and rearrangement pathways
🔹 How reaction mechanism influences product formation

This lecture is ideal for pre-med, chemistry, biochemistry, and STEM students, and is designed to strengthen mechanistic understanding, not just memorization. Perfect for exam preparation, homework help, and building a strong conceptual foundation in alkene chemistry.
