1 s orbital

2 Bonding between two s orbitals This is called a sigma (  ) bond.

3 note: the amount of overlap that gives the lowest energy (most stable)

4 p orbitals Family portrait

5  (sigma) bonds s-s overlap s-p overlap p-p overlap

6 p orbitals again

7  bond (2 overlapping regions form 1 bond) What would be the effect of the orbitals rotating independently?

8 Enter Hybridization The geometries and the angles don’t match orbital shapes.

9 Bring in the mathematicians!

10 Orbitals are combined to form hybrids. s + p + p = sp 2 1/3 s and 2/3 p in character

11 sp 2 again

12 sp 2 (trigonal planar)  (sigma) bonds  bond

13 1/2  bond Find the  bonds the other 1/2 

14 p-orbital left over after hybidization
