Chapter 6 valence bond theory and molecular orbital theory -bring QM back into the picture to understand bonding Valence bond theory easier to do with Pen and paper •hybrid approach that adds Orbitals to lewis structures "hybridization" molecular orbital theory: Apply the equation a whole mo molecule, This molecular orbital Schrodtger's is the result Valence bond theory: 15 or H-H more accurate Sigma (Jorbital: a bonding orbital forms using s orbitals (or Pid, f...)' unstable JOE ond energy Γ (distance between atoms Syable Porbitals! make or I bonds Pi(vt) bond: & loles overlap Jobond bond bonds are usully more Stronger (lower energy) then it bonds hybridizatrun: note that p orbitals are off 90° apart
