A) they are concerted reactions
B) proceed via a cyclic transition state
C) no intermediates are formed
D) all of these

Question

Quizplus · Accepted Answer

Pericyclic reactions are indeed concerted, meaning that all bond breaking and forming occurs simultaneously in a single step. These reactions proceed via a cyclic transition state, where all atoms are geometrically arranged in a cyclic fashion. Because the reaction is concerted, no intermediates are formed. Therefore, all the given options are true.
