Which of these molecular orbitals of butadiene represents the orbital with the lowest energy? двдв "двув двд8. двдв a. с. d.

. The pyridine molecule (C3H;N) is obtained by replacing one C-H group in benzene with a nitrogen atom. Because nitrogen is more electronegative than the C-H group, orbitals with electron density on nitrogen are lower in energy. How do you expect the MOs and energy levels of pyridine to differ from those of benzene?
