Hybridization and Shape
How are hybridization and molecular shape related? i.e how do you determine hybridization from shape or vice versa?

Re: Hybridization and Shape
This chart may help you understand the relation between hybridization and molecular shape.

Re: Hybridization and Shape
Hybridization is directly related to steric number. That is, it directly relates to the number of regions of electron density. From the table shown, both AX2E and AX3 have sp2 hybridization because there are 3 regions of electron density in each. In other words, be careful not to confuse shape with hybridization, since some molecules with the same shape may have different hybridization. For instance, both AX2 and AX2E3 are linear, but hybridization is sp and sp3d, respectively. Hope this is more clarifying!

Re: Hybridization and Shape
Okay, so 2.F.1 says: State the relative orientations of each of the following hybrid orbitals: (a) sp3 ; (b) sp; (c) sp3d2. So if there are multiple shapes that have sp3 or sp2, could there be two answers for part a of this question?

Re: Hybridization and Shape
The number of regions of electron density is equal to the number of hybrid orbitals. We can determine the shape and number of regions on electron density from as VSEPR Formula. Keep in mind lone pairs and bonded atoms both count as regions of electron density. I found this quizlet which provides a nice summary of the relationship for different examples! Hope this helps! :)

Re: Hybridization and Shape
They are connected because the regions of electron density correspond directly to the hybridization. Two regions = sp. Three regions = sp2. Four regions = sp3. And so forth. Double/triple bonds still only count as one region of electron density.

Re: Hybridization and Shape
I wouldn't necessarily base the shape off its hybridization, as hybridization only gives the electron density connections, I would mostly base it off the AXE format, as it allows you to know how many electrons and actual elements its connected to
