1) Is there a relationship between HOMO and LUMo and bonding and antibonding? explain2) Which of the three species ( H2+ , H2 and H2- ) has a HOMO with a node?3) What atomic orbitals create the LUMO for h2-? What orbital for H2+ and/ or H2 more closely resembles the HOMO in H2-? 4) What do the density/potential plots demonstrate about bond order? (provide a specific answer for H2+, H2, and H2-)
