Unformatted text preview: π- bonding. The next orbital is a nonbonding MO with one node that bisects the molecules ↳  i.e., the node passes through the central C atom and eliminates interac0on with the central carbon p- orbital. The highest orbital is a π* (an0bonding combina0on) with two nodes. An;bonding Nonbonding or em pty Bonding The MO diagram gives a different view than that provided by VB theory and orbital occupancy helps to explain the reac0vity observa0ons. HMO Treatment of π- Systems Butadiene: a linear 4- carbon π- system Butadiene has four carbons atoms each possessing a singly occupied p- orbital. ↳  i.e., butadiene has a total of four electrons in the π- system. An easy way to determine butadiene π orbitals is by combining two ethylene units. In order for orbitals to combine,...
