(a) Label endo and exo products above. (b) Show the mechanism of the reaction using the structures above (ignore stereochemistry). (c) Draw a carefully constructed energy diagram that is consistent with the mechanism and the experimental observations. Include the starting material, products, and any intermediates. Label the transition state(s) TS and activation barrier(s) EA. Label the kinetic product and the thermodynamic products (if applicable) on the energy diagram
