This document contains digitally taken, handwritten notes for the conjugated pi systems chapter. It covers topics on HOMO and LUMO structures, energy levels as well as molecule stability. Notes also cover information dienes, their nomenclature as well as their properties. Thoroughly explained subtopics include 1,2 and 1,4 addition, pericyclic reactions, Diel’s - Alder reaction as well as sigmatropic, Cope and Cleissen rearrangements. Notes show mechanism thoroughly and include explanation as n...

This document contains an overview of conjugated pi systems.

Discusses how conjugation works, and how it affects stability and reactivity of a molecule. Includes information about nomenclature, and shows how pericyclic reactions work, including their mechanisms. The diels alder reaction is focused on.
