This damage occurs through a type of organic reaction called a pericyclic reaction. In this episode of Crash Course Organic Chemistry, we’ll explore pericyclic reactions to see how the sun can both give us life, and hurt us, and also look at other important pericyclic reactions, such as the Diels-Alder reaction.Episode Sources:https://cen.acs.org/articles/95/i15/Remembering-organic-chemistry-legend-Robert-Burns-Woodward.htmlhttps://www.nobelprize.org/prizes/chemistry/1950/alder/biographical/ https://www.nobelprize.org/prizes/chemistry/1981/summary/https://www.nobelprize.org/prizes/chemistry/1981/fukui/facts/ https://www.uni-kiel.de/grosse-forscher/index.php?nid=diels⟨=eOhashi, M., Jamieson, C.S., Cai, Y. et al.
