The lowest energy orbital, or LUMO, functions as an electron acceptor and indicates how vulnerable a molecule is to attack by nucleophiles since it has the potential to accept electrons.
What do nodes in molecule orbitals represent?
The node of orbit: an orbital point or plane with no electron density. Constantly surrounded by two or more orbital lobes.
What benzene has the highest electron density out of the following?
The highest number (3) of these H-C bonds are connected to the unsaturated system in compound A (toluene). Thus, it will have the greatest degree of hyperconjugation and the greatest amount of electron density on the aromatic nucleus.
