general hybridization

Postby Ethan Vuong 3G » Tue Nov 28, 2017 1:16 pm

Hi, Im really confused with hybridization right now. I understood it during lecture, but I am lost now. Can someone explain to me a simple way to find the hybrid orbitals. Is it just based of the electrons being shared, or all the electrons including lone pairs?

Hi, Ethan,
You can figure out hybridization by counting the regions of electron density. This includes lone pairs. Therefore, N will sp3 hybridized in NH3 as there are three bonds to hydrogens and one lone pair (4 regions of electron density). Double and triple bonds will still count as one region as pi bonds are formed from p-orbitals and do not participate in hybridization.

all you need to do is count the areas of electron density and add them. for example, 2 areas of high electron density would be sp, 3 would be sp^2, 4 would be sp^3, 5 would be sp^3d, and 6 would be sp^3d^2
