b) The cyclic sulfone $\mathbf{E}$, shown below, undergoes a pericyclic reaction on heating to form compound $\mathbf{F}$. When the reaction is conducted in the presence of ethyl acrylate, $\mathbf{F}$ reacts with it to form a cycloadduct $\mathbf{G}$. Identify the compound $\mathbf{F}$, and draw the structure of the major product $\mathbf{G}$ expected in this reaction sequence. Draw 'arrow pushing' mechanisms for each step, and clearly show the stereochemistry which arises in the product G. Full analysis of the orbital interactions is NOT required. [9]
