How many \(\pi\)-electrons does benzene have?
Answer: 
In a molecular orbital, the relative energy of the orbitals can be qualitatively determined by ranking them by
the number of bonding interactions they have. A bonding interaction can be represented as constructive
overlap of two adjacent orbitals and an anti-bonding interaction is represented by destructive overlap:
