![1. a) (Give brief answers)
Consider the molecule Cl-F, assume both atoms to use p orbital.
According to MO theory, the total wave function for the two electrons in
the bonding molecular orbital can be written as:
YaF=Y1). Y b(2) = YA(1).P A(2)+ YA(1). Y B(2)+ YB(1).P B(2)+ PA(2) . Y B(1)
Where YA and YB are the wave functions for the p orbitals of
fluorine atom A and chlorine atom B respectively, and 1 and 2
are the two p electrons
