Octet Rule, Lewis Structures & Formal Charge | Chemical Bonding | Class 11 (Hindi) By Tripti Rawat

This lecture cover important concepts from Class 11 Chemistry, Chapter – Chemical Bonding and Molecular Structure. We begin by understanding why atoms bond with each other and how they attain stability, followed by a detailed discussion of the Octet Rule and its significance in ionic and covalent bonding. We then move on to Lewis Dot Symbols, learning how valence electrons are represented for different elements, and go through the step-by-step method for drawing Lewis structures, with CO₂ and H₂O explained as worked examples. Next, we cover the concept of Formal Charge — what it means, how it is calculated using the formula, and how it helps us identify the most stable Lewis structure, especially in molecules involving resonance like ozone (O₃). Finally, we discuss the limitations of the Octet Rule, covering incomplete octets, odd-electron molecules, and expanded octets with examples like BF₃, NO, PCl₅, and SF₆. This topic is an important part of Class 11 board exams and also forms the base for concepts used later in JEE and NEET Chemistry, so make sure to watch the full video for complete clarity. 🗣️ Language: Hindi 📖 Based on: NCERT Chemistry Class 11, Chapter – Chemical Bonding and Molecular Structure 👩‍🏫 Taught by: Tripti Rawat, PGT Chemistry 🔔 Subscribe for more Class 11 & 12 Chemistry lectures. 👍 Like this video if it helped you understand the concept. 💬 Drop your doubts in the comments — I read and reply to them. #ChemicalBonding #OctetRule #LewisStructure #Class11Chemistry #NEETChemistry #JEEChemistry
