Oxymercuration–Demercuration Reaction – Mechanism Explained | Alkenes | BSc Chemistry | Easy Explanation In this video, we will understand one of the most important reactions of alkenes — Oxymercuration–Demercuration. This reaction is widely used to convert alkenes → alcohols without carbocation rearrangement. A simple, exam-oriented explanation with mechanism and examples is provided — perfect for BSc Chemistry, Semester 1–2. 📌 Topics Covered What is Oxymercuration–Demercuration reaction? Addition of water across double bond Step-by-step mechanism of oxymercuration Formation of Mercurinium ion Nucleophilic attack by water Formation of organomercury alcohol Demercuration using NaBH₄ Markovnikov addition Why no rearrangement occurs Important exam questions with solutions Examples for BSc / Competitive exams 🧪 Reaction Summary Alkene + Hg(OAc)₂ + H₂O → (Oxymercuration) → Organomercury Alcohol Organomercury Alcohol + NaBH₄ → (Demercuration) → Alcohol This gives a Markovnikov alcohol without carbocation shift — making it one of the cleanest hydration methods. ⭐ Why This Reaction Is Important? ✔ Gives Markovnikov product ✔ No rearrangement ✔ No strong acids needed ✔ Works on most alkenes ✔ Very high yield 📝 Suitable for: BSc Chemistry (1st Year, 2nd Year) Organic Chemistry Students JEE/NEET Foundation Competitive Exams 🔔 Watch the Complete Video for: Mechanism diagrams Solved questions Easy tricks to remember #oxymercurationdemercuration #alkenes #organicchemistry #bscchemistry #reactionmechanism #markovnikovrule #hydrationofalkenes #chemistrytutorial #chemicalreactions #easyexplanation 📩 Connect With Me 📌 Join Telegram for Notes & Updates: 👉 Your Telegram Link Here
