1) Use your white board to draw the Lewis structure for ozone, O3.

2) What does the word hybridization mean? Use your own words.

While you are doing warm up I will come around and check HW #24. (except 4th period)

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 ….

-Learn what a sigma bond looks like

-Learn what a pi bond looks like

-Understand the concept of orbital hybridization and how it changes the bonding in an atom such as carbon

When two atomic orbitals combine to form a bond along the axis between two atoms … we call it a sigma

bond ()

When two “p” orbitals combine side by side we say they overlap to form a pi () 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

The electron structure of a carbon atom can be written as:

Based on this model, we would predict that carbon atoms should form two covalent bonds??!!

Instead carbon atoms almost always form 4 bonds.

Why????

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.
