Is molecular shape determination just a matter of memorization of different bonds and lone pairs?

Molecular shape determination can be reasoned out by first drawing the Lewis structure and then considering the repulsion of valence electrons and lone pairs. The names of molecular shapes do have to be memorized though.

I'm assuming we will need to know the names of the shapes for both our test and the Final.

You will have to memorize the names of the molecular geometry but you can figure out the regions of electron density from the Lewis structure. Hope this helps!

I think that it's more reasonable to reason the shape rather than memorizing. From seeing its arrangement like tetrahedral, trigonal pyramidal, or trigonal planar, we can see if the molecule has lone pairs and whittle down from there. We would have to know both its arrangement and shape, like if it's bent.
