The peculiar properties of the three-membered ring (C3 ring) in cyclop
ropane and its derivatives are due to characteristic bonding and elect
ronic effects. Contraction of the atomic orbitals (AO's) composing the
C-C bonding molecular orbitals (MO's) of a1 symmetry favors stability
of the C3 ring. Expansion of the e' HOMO AO's contributes to the form
ation of peripheral ''pseudo-pi bonds''. The stability of the C3 ring
also correlates with substitution of the ring.
