2 lone pairs

[danielruiz1G]

On a structure that has 2 lone pairs on the center atom, how are we supposed to know when the strcutes go on the top and bottom or both stay on the top side?

I think it’s important to have symmetry when drawing structures

Hope this helps

Yes I think that they go on opposing sides so that they do not pull on just one side of the molecule

Remember that a Lewis Structure is just a 2D model of a 3D shape. So for example, in water, with a tetrahedral shape, every region of electron density is next to every other, so there is no "top" or bottom. With Lewis structures, it doesn't matter where you draw the lone pairs because it doesn't necessarily mean anything in terms of the actual molecular shape.

lone pairs should be placed as far apart from each other as possible since they have a very strong repulsion this would mean they should be placed on opposite sides (top and bottom)

it does not matter whether you put it on the top or at the bottom. The only thing you only need to pay attention to is to put these two dots on different sides
