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 |
