Complete the Molecular Orbital diagram. As part of your answer, define all of the terms used and explain the meaning of any symbols. There is no need to apply the frontier orbital approach for this pericyclic reaction.

(b) Identify and classify the type of pericyclic reaction shown below and use Frontier Orbital Analysis to identify the reaction conditions under which the reaction will proceed. As part of your answer, draw the appropriate Molecular Orbital diagrams and define all new terms and symbols used as part of your answer.
