Calculating Bond Order in Organic Resonance Structures using Average Valence Bonds in Chemistry

Bond order is defined as a quantitative measure of electron pair bonding between atoms within molecules exhibiting resonance hybrids. The core principle states that for bonds participating in delocalization, the bond order is calculated as the arithmetic mean of the number of bonds across all contributing canonical structures divided by the count of those specific atomic connections involved in the system. This theoretical framework operates strictly within quantum chemistry and organic molecular orbital theory to describe electron distribution density rather than discrete single or double linkages found in static Lewis representations.
