How to figure out hybridization

Postby JooHyun Koh 1H » Mon Jun 11, 2018 7:57 pm

To figure out hybridization, say SO2 for example, do u only need to look at the number of sigma bonds and lone pairs? So would the hybridization on sulfur in SO2 be sp2 because it has 2 sigma bonds and one pair of lone pair electrons?

In a way yes, but more accurately, you look for regions of electron density.

Does a lone pair count as one region of electron density? or do you count both electrons each as a region of density?

when we look at so2 we know that it has three things attached (when you include the lone pair) to the central atom, S. this means that we are going to fill up three regions, starting with the s-orbital and moving onto the p orbital. We'll get sp2 for the hybridization. When we look at the VSEPR formula we have AX2E. Whatever is after the X will be the amount of sigma bonds we have, so 2, and then we need to look at the hybridization to determine the number of pi bonds we'll have. We have sp2 and we know that the p orbital needs 3 to be full. That means we add one pi bond so the bonds we have will be 2 sigma and 1 pi.

You're looking for regions of electron density. When looking at the VSEPR formula for SO2 you see it would be AX2E (3 total) which in turn will equal to sp2

When you say regions of electron density, are you referring to using the periodic table? Could you explain how to look for this please?
