Hybridization connection

Postby Andrea- 3J » Thu Nov 29, 2018 9:31 pm

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
For three, the hybridization would be
For four, the hybridization would be
For five, the hybridization would be

I find this table to be helpful (it only goes to , 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.
