Lecture
This lecture delves into the intricacies of reaction mechanisms, focusing on the concept of aromaticity. It explores the Nucleus Independent Chemical Shifts (NICS) method, advantages, and disadvantages. The lecture also covers ring strain, aromaticity measurements, and the impact of o-aromaticity on cyclopropane and cyclobutane. Additionally, it discusses the potential energy surface (PES) and the importance of geometry optimization in understanding energy minima and transition states.
