6. Is the thermal (3+2) cycloaddition between allyl anion and ethylene to give the cyclopentyl carbanion, shown below, a thermally allowed or forbidden reaction? To answer, draw the molecular orbitals for HOMO of the ally! anion and LUMO of ethylene and clearly orient the orbitals in such a way that the orbital interactions are clear. Label the two key orbital interactions as bonding (in-phase) or antibonding (out of phase). (11 pts) G

Part 2: Reactivity ore on this section, no more than 5 errors are permitted. reaction is a (4+2] cycloaddition reaction used to form cyclohexene. Shade in the orbitals appropriately for the ground state of butadiene and HOMO and LUMO and draw in all electrons ethene. Label the Ground State Ground State Shade in the orbitals involved in the reaction and indicate constractive or destructive overlap for thermal conditions. Hint: The LUMO comes from ethene...
