Chemistry Class 12 Sem 4 Unit-4 Class 04 : Valence Bond Theory (VBT)

​In this lecture, we dive deep into Valence Bond Theory (VBT), a crucial topic in Chapter 4: Coordination Compounds for Class 12 Chemistry. Understanding VBT is essential for predicting the geometry, hybridization, and magnetic properties of complex compounds. ​Whether you are preparing for Board Exams, JEE, or NEET, this session will simplify the most complex concepts of metal-ligand bonding. ​What You Will Learn: ​The Postulates of VBT: How metal ions provide vacant orbitals for ligand bonding. ​Hybridization States: Understanding sp^3, dsp^2, sp^3d^2, and d^2sp^3. ​Geometry Prediction: How to determine if a complex is Tetrahedral, Square Planar, or Octahedral. ​Inner vs. Outer Orbital Complexes: Why some complexes are "High Spin" and others are "Low Spin." ​Magnetic Behavior: How to calculate the spin-only magnetic moment (\mu) using the formula \mu = \sqrt{n(n + 2)}. ​Key Examples Covered: ​[Co(NH_3)_6]^{3+} (Diamagnetic, Inner Orbital) ​[CoF_6]^{3-} (Paramagnetic, Outer Orbital) ​[NiCl_4]^{2-} vs [Ni(CN)_4]^{2-} (Geometry differences) 📌 Practice Worksheet: [Link to Questions] ​Don't forget to: ✅ Subscribe for more Chemistry tutorials. ✅ Like the video if you found it helpful. ✅ Comment your doubts below—I'll be answering them! ​#Class12Chemistry #VBT #CoordinationCompounds #ChemistryLecture #JEEChemistry #NEETPreparation #ValenceBondTheory
