Chemical Bonding: Resonance Structures and Covalent Bonds

This lecture covers the concept of resonance structures in chemical bonding, focusing on benzene as a typical example. It explains how the load is distributed over the three oxygen atoms, leading to the formation of resonance structures. The lecture also discusses the strength of covalent bonds and the kekule structure. Furthermore, it delves into exceptions to the octet rule, hypervalent compounds, and the formation of covalent coordination bonds. The importance of radicals, molecular orbitals, and the charge of atoms in molecules is also explored, along with the VSEPR model for predicting molecular shapes.
