Concerted transition state
In organic chemistry, a pericyclic reaction is the type of organic reaction wherein the transition state of the molecule has a cyclic geometry, the reaction progresses in a concerted fashion, and the bond orbitals involved in the reaction overlap in a continuous cycle at the transition state. Pericyclic reactions stand in contrast to linear reactions, encompassing most organic transformations and … WebSay, a concerted transition state involves the breaking of two bonds and the associated making of two new bonds. Does each bond making/breaking has a corresponding …
