Hello everyone. So in this video we're given this three D representation right over here of a molecule and we're trying to determine the electron geometry. Or geometries of this. So take a look at this structure here. This three D. Model shows a bent molecular geometry. Let's go ahead and actually label that. So again we have a bent molecular geometry. So knowing what makes a bent molecule or what gives his name Is that we have one or 2 lone pairs. I just put lone pairs as L. P. For short. So if we have one lone pair then we can possibly have the electron geometry being. Let's go ahead and write this down. So one lone pair. The electron geometry is tribunal planner electron geometry. Now if we have two lone pairs then we can have the electron geometry being tetrahedron. Alright so the possible electron geometries is going to be a tribunal planner as well as tetrahedron. And it's just knowing that the molecular geometry is composed of either one or two lone pairs. And from that we can then follow our little guide. That's probably given to you in your textbook or by a professor that when we have these two bonds and one lone pair or two lone pairs will have these electron geometries. Alright. Everybody. Hopefully this helps and have a great rest every day
