5. Butadiene has 4 atomic orbitals involved in its conjugated system. Four possible arrangements of these atomic orbitals into molecular orbitals are shown below. The shading of the lobes indicates whether the sign of the wavefunction is positive or negative. For each of these molecular orbitals (A through D), answer the following questions: A Relative energy: Relative energy: ugug Wavefunction: Wavefunction: Relative energy: Relative energy: Tu 909 Wavefunction: Wavefunction: a. Draw a line where each node will occur. b. What is its energy relative to the other orbitals ( 1= highest, 4= lowest)? c. Is it a bonding or an antibonding MO? (circle v or e ) d. Write the wavefunctions for each MO in terms of the 2p atomic orbitals (AOs) that contribute to the pi MO. Let each AO be indicated by where n=carbon number in the chain. Include coefficients, assuming that all atomic orbitals contribute equally to the MO
