Concepts in Inorganic chemistry - Lecture 4 | Electron Domains, Bond Angles & Shapes |

Описание: Welcome to Concepts in Inorganic Chemistry I | Lecture 4: VSEPR Theory & Molecular Shapes ⚛️

In this lecture, we explore how molecules adopt different 3-dimensional shapes based on the repulsion between electron pairs. Using the VSEPR (Valence Shell Electron Pair Repulsion) Theory, we learn how to predict molecular geometry starting from simple Lewis structures.

🎯 Topics Covered:
• Why molecular shape matters in chemistry
• Electron domain theory and repulsion
• Bonding pairs vs lone pairs
• VSEPR basic geometries (linear, trigonal planar, tetrahedral, etc.)
• Molecular geometry vs electron domain geometry
• Axial vs equatorial positions
• Shapes of molecules with lone pairs (bent, trigonal pyramidal, T-shape, etc.)
• Worked examples: CO₃²⁻, NO₂⁻, SF₄, ClF₃, BrF₅, ICl₄⁻
• Effect of lone pairs and multiple bonds on bond angles

💡 Why Watch:
Understanding molecular geometry is essential for predicting the physical, chemical, and reactive properties of substances. This video provides clear explanations and visual examples ideal for university chemistry students, A/L students, and self-learners.
