Cation Intermediates and Alkene Reactions - Formation, Addition, and Stability

Explore cation intermediates, alkene reactions, and reaction mechanisms in this 51-minute organic chemistry lecture from Yale University. Delve into bridged pentavalent carbon structures as intermediates in SN1 reactions, examine stereochemical inversion through ion pairs, and compare perspectives of preparative and mechanistic organic chemists. Investigate electrophilic addition to alkenes, analyze reaction yields in viscous solvents, and utilize the NIST Webbook to understand alkene stability. Cover topics including cation rearrangement, SN1 and E1 mechanisms, competing reactions, rate-limiting molecular rotation, and isomeric alkene thermochemistry.
