Molecular shape on test

Postby Maria Solis Disc 1G » Mon Nov 19, 2018 8:45 pm

For the final, and test 3, will we be expected to know how to draw molecules, using electron densities (including the hybridized and non-hybridized models).

I believe professor lavelle said we would not need to know how to draw the shapes. Just the lewis diagrams and know what shape it is but not actually drawing it.

I believe that we will be expected to be familiar with how they look but we won't actually need to draw them ourselves. As long as we can identify them and know how the various shapes are made, I think we should be fine.

I believe we need to predict the bond angle based on the lewis structure as well as hybridization.

While we won't be required to draw any 3D shapes of molecules, we will be required to know the shapes, bond angles, hybridisation, and how to draw the Lewis structures of molecules. If you start from drawing the Lewis structure, you can get everything else from VSEPR theory so you're good!

My TA specified that only one-dimensional Lewis structure diagrams will be necessary for 14A, and shape should be known but does not need to be drawn out.
