| Hybridization- |
| the mixing of orbitals |
| Linear- SP Trigonal Planar- SP2 Bent- SP3 Tetrahadral- SP3 Pyramidal- SP3 Distorted tetrahedral- SP3d Octahedral- SP3d2 |
| Double or Triple bonds are joined to for one big one. |
| A triple bond is made up of one sigma bond and 2 pi bonds. |
| A sigma bond results from head to head overlap of atomic orbitals |
| Free rotation may occur around sigma bonds but not double or triple bonds |
| The Molecular Orbital Theroy- explains magnetism of molecules sigma-2p* ________ pi- 2p*____ ______ sigma-2p __________ pi- 2p _____ ______ sigma-2s * __________ sigma-2s ___________ sigma-1s*_______________ sigma-1s_______________ |
| Paramagnetism- attached by magnetic field Diamagnetism- repelled by magnetic field |
