You are expected to comment on and interpret more the results. Make sure you check for imaginary frequency each time you optimise a structure whether it is a minimum or a TS and state why it is important to do. Exercise half finished.

Both HOMO and LUMO cis butadiene are antisymmetric? Could analyse the transition state orbitals in terms of the reactant orbitals, discuss chanes in bond length on forming the transition state, discuss the symmetry requires for the reaction to be allowed. Indicate what the imaginary frequency for the transition state was. For maleic anhydride could record and discuss the activation barriers of the two transition states.
