finding the shape of a molecule

Postby Veronica Macias 3K » Sun Nov 29, 2020 11:21 pm

To find the shape of the molecule do you need to draw the best lewis structure or will any lewis structure give you the correct shape?

I think when we are trying to find the shape of a molecule, you have to draw/use the most stable lewis structure, but I am not very sure. This is also something that I wanted to know as well.

Well, each lewis structure that is possible will have a distinct shape. The question is if that shape would really occur. If you are looking for the shape that will exist, find the lewis structures that will exist.

I think that the most stable Lewis structure is usually the one we use to decide the shape of a molecule, or at least that is what Dr. Lavelle did in his lectures.

the VSEPR model is used to determine the shape

You should draw the most stable Lewis structure to find the molecule's geometric shape.

The most stable lewis structure is what you should use as a template for figuring out the shape/structure of a molecule.
I have a hard time visualizing 3D models as well so I use this cool website that you can search any structure up and it provides you with a 3D model to interact with! This was helpful o me in understanding where we get the shapes for molecules from!!
