when to use hybridized orbital?
« on: December 09, 2012, 04:29:35 PM »

Hi.

I am wondering when should we use hybridized orbital?
For PH3, we don't use hybridized orbital because it could be described by  the valence shell method.
p: [Ne]   3s: :spinpaired:   3p:  :spinup:  :spinup:  :spinup:

And we have 3 up. so the 3 extra electrons from hydrogen could fit into there. Therefore we don't need hybridized orbital.
But when do we need it?

p only has 3 unbound p orbital.
Therefore, you need sp2d2 hybri orbitial
