The impact of how orbitals interact on reactivity is introduced before looking at orbital interaction in different reaction types and the effect on transition states. Rearrangement reactions of hydroboration, Baeyer-Villiger reaction, Beckmann rearrangement and Pinacol reaction are given. Effect of orbital interactions on conformation is explored through ethane and anomeric effect on 6-membered rings and the consequences of it. The Diels-Alder reaction is introduced and explored through its sele...
