Abstract

The hybridization in tricyclopropylidene and tetracyclopropylidene
has been calculated by the method of maximum overlap.
The results show that the hybrids describing the central ring have
more s character than those in cyclopropane and cyclobutane:
sp3·02 and sp3·31 as compared to sp3·86 and sp3·47 respectively. Consequently the central bonds in the two molecules investigated . are
stabilized by the cyclopropyl substitutions. An interesting comparison
between the maximum overlap hybridization and hybridization
based on more elaborated calculations is made.
