GOC-2 Lecture 11 Part 1 | Free Radical Substitution Reaction | Halogenation of Alkanes | HELPER Condition Namaste Dear Students 🙏 Welcome to Class 12 Organic Chemistry – GOC-2 Lecture 11 (Part 1). In this lecture, Krishna Kumar Sah (ChembyKKSir) transitions from EAS to the world of Free Radical Substitution Reactions (FRSR). This is the most characteristic reaction of alkanes and occurs at sp^3 hybridized carbons, specifically focusing on Alkylic, Allylic, and Benzylic positions. Key Highlights of this Lecture: ✅ The HELPER Condition: A foolproof trick to remember when Free Radical mechanisms occur (High Temperature, Electricity, Light (UV), Peroxide, and other Radicals). ✅ Mechanism Steps: Detailed explanation of the three core stages: Chain Initiation: Homolytic fission and formation of radicals. Chain Propagation: The "Workhorse" step where products are formed. Chain Termination: How the reaction finally stops. ✅ Reactivity & Selectivity: Why Bromination is more selective than Chlorination. ✅ Halogenation Trends: A deep dive into Chlorination, Bromination, Fluorination (Explosive), and Iodination (Reversible). ✅ Substrate Focus: Reactivity of sp^3 hydrogen at Alkylic vs. Allylic vs. Benzylic positions. This lecture is fundamental for understanding hydrocarbon chemistry and is highly recommended for NCERT, NEET, and JEE Main/Advanced aspirants. 🔥 Connect with ChembyKKSir: 🔹 Instagram:   / chembykksir   🔹 WhatsApp Channel: https://whatsapp.com/channel/0029Vb6F... 🔹 Facebook: https://www.facebook.com/share/1ACSwY... 🔹 LinkedIn:   / krishna-kumar-sah-13708661   🔹 Telegram: https://t.me/chembykksir 🔹 YouTube: https://www.youtube.com/ ‪@ChembyKKSir‬ #GOC2 #FreeRadicalSubstitution #FRSR #Alkanes #Halogenation #Chlorination #Bromination #OrganicChemistry #ChemistryByKKSir #JEE2026 #NEET2026 #ReactionMechanism #Class12Chemistry #AllylicSubstitution #BenzylicSubstitution #HELPERCondition #ChembyKKSir HASHTAGS (FOR THE TAG SECTION): GOC2, FreeRadicalSubstitution, FRSR, Alkanes, Halogenation, Chlorination, Bromination, OrganicChemistry, ChemistryByKKSir, JEE2026, NEET2026, ReactionMechanism, Class12Chemistry, AllylicSubstitution, BenzylicSubstitution, HELPERCondition, ChembyKKSir, HomolyticFission, ChainInitiation, JEEAdvancedChemistry 💡 Suggested Pinned Comment: "Namaste Students! In this lecture, we decode the HELPER condition—your secret weapon for identifying Free Radical Substitution. Which step of the mechanism do you find most interesting: Initiation, Propagation, or Termination?
