p electron bond order
· We can also
define a quantity which measures the strength of a p-electron bond
between two atoms.
· This quantity
depends on the electron density which is shared between two atoms:
p electron bond order for a-b bond (pab):
again ni is the
number of electrons in molecular orbital i.
If all the occupied molecular orbitals
have two electrons in them then all the ni = 2 and:
