### Hybridization connection

How do I connect hybridization with lewis structures, molecular formula, molecular geometry and polarity?

Table 2f.1 does a pretty good job of explaining this correlation in 7th edition, but for example.
If electron arrangement is linear, then the number of atomic orbitals=2, thus the hybridization is sp, and there are 2 hybrid orbitals.

In addition, you can count the regions of electron density to find the hybridization. In the lewis structure for a molecule, single bonds, multiple bonds (double, triple), radicals, and lone pairs each count as one region of electron density.

For two region of electron density, the hybridization would be $sp$
For three, the hybridization would be $sp^{2}$
For four, the hybridization would be $sp^{3}$
For five, the hybridization would be $sp^{3}d$

I find this table to be helpful (it only goes to $sp^{3}$, but it should give you an idea of how everything relates):

Polarity is dependent on the shape of the molecule. For example:

If a molecule is linear, it is:
-Polar if the atoms on either end are the same
-Nonpolar if the atoms on either end are different

You can look up the rest (it would be a lot to write here).

Molecular formula would likely be given already I think.

I hope this kind of helps relate these different concepts together.
