### 4.31

How do you find the relative orientation of hybrid orbitals? (i.e. sp^3 and sp^3d^2)

What I do is I add up all of the exponents (sp=2, sp^2=3,etc.). The sum I relate to the molecular structures so 2 would be linear, 4 is tetrahedral, etc.

hope this kinda helps. i know its a bad explanation.

You can use regions of electron density to easily determine shape and hybridization and vice-versa. For example, 3 regions of electron density corresponds to both a trigonal planar shape and sp^2 hybridization (s p p). 4 regions of electron density corresponds to a tetrahedral shape sp^3 hybridization ( s p p p).
