VSEPR Theory - Basic Introduction

This chemistry video tutorial provides a basic introduction into VSEPR theory and molecular structure. It contains examples and practice problems of drawing lewis structures along with the correct molecular geometry. Structures include the tetrahedral shape, bent, linear, trigonal planar, and trigonal pyramidal molecular geometry as well as their bond angles.

@@electro_yellow9295 Personally my professor sucks so I have to look up all the topics he tries to explain in class and teach myself. We don't even have a textbook, he teaches through handouts. So it's not that they aren't a good student, probably just a bad teacher. The fact that they are watching this video, trying to learn and understand it makes them a good student. 🙄

[@bellefeu4933]

I just want to mention that the bond angle for trigonal pyramidal molecules, starting from NH3, is 107*. As you go down and to the left on the periodic table, elements get larger, meaning PH3 is larger than NH3 and AsH3 is larger than both PH3 and NH3; AsH3>PH3>NH3. Because these are larger molecules, their shells are further apart, making the bonds longer and weaker. This subsequently reduces the bond angles as the molecule gets larger. Unfortunately, just gotta memorize the numbers, but realize that it is NOT 107*. NH3 = 107* PH3 = 93.5* AsH3 = 91.8*
