1. (1 pt) Show the expected product of the Diels-Alder reaction below.

2. (3 pts) For the cation below, a) write three resonance forms, b) show the energy levels and the number of electrons in each level, and c) write an orbital symmetry picture of the HOMO of the cation.

3. (3 pts) The reaction below generates an intermediate with two resonance forms and two corresponding products. Write both resonance forms of the intermediate and the structures of both products, indicating which product is the result of thermodynamic control (label TC) and which is the product of kinetic control (label KC).

4. (3 pts) The reaction below also generates an intermediate with two resonance forms and two corresponding products. Write both resonance forms of the intermediate and the structures of both products, indicating which product is the result of thermodynamic control (label TC) and which is the product of kinetic control (label KC).
