Notes:
The belgian chemist Paul Havrez (1838-1875) proposed two highly symmetrical, space-filling models for the benzene molecule, only a few months after Kekulé's seminal proposal of a cyclic benzene structure. One of these models is characterized by the revolutionary assumption of equal 3/2 bonds between all neighbouring carbon atoms, in sharp contrast to Kekulé's formula with alternating double and single bonds. With Considerable hind-sight, Havrez's model could be considered as a forerunner of the benzene structure with delocalized π bonds.
