Organic Chemistry: Multiple Bonds and Delocalization

This lecture covers the concept of multiple bonds in organic chemistry, focusing on bond lengths, energy barriers, and the Valence Bond Model for cumulated, isolated, and conjugated double bonds. It also explores the Electron in a 1D Box model, Frontier Orbitals, and the delocalization of electrons in cyclic conjugated multiple bonds. The discussion extends to resonance structures, bond orders estimation, and the impact of electron-donating and electron-withdrawing groups on electron density and reactivity in conjugated systems.
