Warm up. D raw the Lewis structure for ozone, O 3 . What does the word hybridization mean? Use your own words. Warm up. Warm up. Resonance. A resonance structure is a structure that occurs when it is possible to draw two or more valid electron dot structures.

A resonance structure is a structure that occurs when it is possible to draw two or more valid electron dot structures.
In the case of ozone, neither structure actually exists, but rather the actual bonding is an average of the two structures.
Definition of hybridization ….
When two atomic orbitals combine to form a bond along the axis between two atoms … we call it a sigma bond (s)
When two “p” orbitals combine side by side we say they overlap to form a pi (P) bond
Pi bonds exist when we have double and triple bonds
Single bond – 1 sigma bond
Double bond – 1 sigma and 1 pi bond
Triple bond – 1 sigma and 2 pi bonds
Based on this model, we would predict that carbon atoms should form two covalent bonds??!!
Regular Carbon Aufbau Diagram
1 s + 3 p = 4 sp3
(All 4 orbitals are now equal at the 2nd energy level)
Electrons must be distributed among the new orbitals. Since these hybrid orbitals are equal in energy, the electrons must distributed according to Hund’s Rule.
