boring molecular geometry question!

[Kneecoal]

lame-o, but kaplan only goes into basic molecular geometry, meanwhile the textbook i'm referencing goes into all the sub-geometries, like bent and t-shaped. would you recommend to know the sub-ones, too?

 

[iwannabadentist]

know linear, bent (1 and 2 lone pairs), trigonal planar tetrahedral, trigonal pyramidal, and trigonal bipyramidal.
that should be enough...
