### Orientation of Hybrid Orbitals: 4.31

How do we know the relative orientations of hybrid orbitals: sp, sp2, sp3, sp3d, sp3d2 (such as it is asked in problem 4.31)?

They are just like when you are figuring out the shape of the molecules, only you don't exactly call them "tetrahedrons" or "trigonal planners" and such. Instead, you say that the orbitals are oriented towards the corners of [insert shape] (with the exception of the linear shape, of course, because, well, it's linear).

So when you have sp3d for example, you have 5 areas of (high) electron densities, and their orbital are oriented toward the corners of a trigonal bipyramidal.

Thank you!
