2
1 s orbital
3
2 Bonding between two s orbitals This is called a sigma ( ) bond.
4
3 note: the amount of overlap that gives the lowest energy (most stable)
5
4 p orbitals Family portrait
6
5 (sigma) bonds s-s overlap s-p overlap p-p overlap
7
6 p orbitals again
8
7 bond (2 overlapping regions form 1 bond) What would be the effect of the orbitals rotating independently?
9
8 Enter Hybridization The geometries and the angles don’t match orbital shapes.
10
9 Bring in the mathematicians!
11
10 Orbitals are combined to form hybrids. s + p + p = sp 2 1/3 s and 2/3 p in character
12
11 sp 2 again
13
12 sp 2 (trigonal planar) (sigma) bonds bond
14
13 1/2 bond Find the bonds the other 1/2
15
14 p-orbital left over after hybidization
16

16 sp 3 hybridization 1/4 s and 3/4 p
