Valence Bond Theory (VBT) Sigma and Pi Bonds | Lecture 8 | Chapter 3 | Fsc 1st year Chemistry

📚 Welcome to Chemistry Lover! In this lecture (Lecture 8, Chapter 3 – Chemical Bonding), we will explore Valence Bond Theory (VBT) in detail along with the formation of Sigma (σ) and Pi (π) Bonds. Understand how atomic orbitals overlap to form covalent bonds and the difference between sigma and pi bonding using clear visual examples and board-based teaching. 🌟 This lecture is essential for all FSc 1st year students who want to build a strong foundation in chemical bonding concepts — especially for MCQs, short questions, and board exams. 🔍 What You'll Learn: Postulates of Valence Bond Theory What is a Sigma (σ) Bond? What is a Pi (π) Bond?
