Chemistry: Electronic and Molecular Geometry

General Chemistry help! A simple tutorial to help you visuallize the electronic and molecular geometries predicted by the valence-shell electron-pair repulsion, VSEPR, models.




This tutorial uses both 3-D chemistry models and 2-D diagrams.

Thank you for doing this!! You explain this way better than my Chem teacher!!! :)

How do you know if it is polar or not?

This was so helpful! Thank you so much for this video! :D

This is a great video. I'm glad i checked it out! However, I have a question. How come the molecular geometry of the square pyramid (Octahedral) looks alot like that of the trigonal bipyramid (Trigonal Bipyramid)? From my understanding, the square pyramid is supposed to have one lone pair of electrons. Did you just simply forget to draw it on the diagram or assumed that we'd know there was a lone pair present? I'd like to know as soon as possible. Thanks in advance.

yes omg thank you so much.. this helped a tonnnnn... :)))

@zacmiley12 The lone pairs are placed beside the least electronegative atom (which occupies the central position). For example, in IF5, there is one lone pair which is placed beside the iodine atom in the central position.

her hands scare me!!!



[socerjjj]

very clear and concise. thank you...my prof tried to explain this to 100 students with balloons and everyone was lost...

[zacmiley12]

Uhm how do you know where to place the lone pairs? I had heard that they are placed where the 90 degree angles are?? I'm really confused please help.

nice that was so good

but why arent you my chem teacher!!!

Thank you! Now this actually makes sence.
