chapter11 Molecular shapes and bond theories

In this lesson, we explore how atoms arrange themselves in three‑dimensional space and why molecules adopt the shapes they do. Understanding molecular geometry and bonding theories is essential for predicting polarity, reactivity, and the physical and chemical properties of substances. You’ll learn: • How valence electrons and electron domains determine molecular shape • How to use VSEPR theory to predict electron geometry and molecular geometry • How lone pairs influence bond angles and distort ideal shapes • The difference between electron geometry and molecular geometry
