Any Other Shapes?

Postby Jose Lupian 1C » Sun May 27, 2018 10:31 pm

Are there any other shapes that we should take into consideration that Professor Lavelle hasn't covered yet?

I am fairly certain that we covered every shape listed in the textbook. You can refer to Figure 4.7 on page 118 in the textbook for a table of all the shapes.

Will we learn the VSEPR model for molecules with one or more lone pair? So far, we've only learn the basic geometry for molecules with zero lone pairs.

There are other possible shapes, but we would just need to know the ones in the book which Dr. Lavelle went over in class.

So there is only like 5 shapes we need to know?

Are the shapes in the front of chapter 4 the only shapes known in total? Or are they only few of the many shapes possible?

We will most likely need to know the "Bent" shape, which is what water is. It would be a tetrahedron but its bond angles are different due to the lone pair of electrons acting as one of the regions of electron density. I would at least remember that lone electron pairs have a different effect on the shape and that VSEPR only counts the atoms and not the electron pairs for the general structure (if anyone can clarify this part of the rule that would be great since I don't fully understand it).

Best,
Jack Dias
