Basis functions: H 1s; F 2s, 2p
Energy of basis functions : 1s Z = 1, F, Z* >1 therefore 2s, 2p lower in energy
BO = 1 σ bond more centered on F so electron density is favors this atom
This is consistent with our ideas about electronegativity
HF
Basis functions: H 1s; F 2s, 2p
Energy of basis functions : 1s Z = 1, F, Z* >1 therefore 2s, 2p lower in energy
BO = 1 σ bond more centered on F so electron density is favors this atom
This is consistent with our ideas about electronegativity
CO
basis, 2s, 2p on each atom; O orbitals a little bit lower
BO = 3 lone pair on C accounts for Lewis basicity
