(i) Draw the chemical structure of product F of the reaction shown in Figure 2, where E undergoes an electrocyclic ring closure under thermal conditions. Include the appropriate stereochemistry in your answer and account for the stereochemical outcome in terms of the Woodward Hoffman rules. (ii) Shown in Figure 3 is an example of a [4+2] cycloaddition reaction. Draw the chemical structure of the product G and draw the mechanism for the reaction using curly arrows. Figure 3
