Chapter 3 - Bonding
| Term | Definition |
|---|---|
| molecular orbitals | two atomic orbitals combined |
| bonding orbital | lower E, when the signs are the same when combining atomic orbitals |
| Antibonding orbital | higher E, when the signs are diff when combining atomic orbitals |
| sigma bond | head to head overlap; strong |
| pi bond | parallel overlap; weak |
| single BO | sp3, sigma bond, long bond length, small E |
| sp3 | tetrahedral shape |
| double BO | sp2, trigonal planar, sigma and pi bonds, medium bond length and medium E |
| triple BO | sp, sigma pi pi bonds, linear, large E, small bond length |
