Square Planar

Postby Henry Krasner 1C » Thu Nov 15, 2018 1:04 pm

I get that when there are 4 bonds and 1 lone pair, the shape is going to be a seesaw. However, in what situation would the shape be square planar?

Square planar molecular geometry occurs when there are 4 atoms and 2 lone pairs bonded around the central atom

If the electron geometry is an octahedral and there are 2 lone pairs, then the molecular shape will be square planar.

It is also important to remember that there has to be 6 regions of electron density in order for there to be a square planar shape. That is, it is different from tetrahedrals, though they will look similar.

Are all square planar structures polar unless they have 4 of the same type of atom?

Try to think about it logically. Square planar has 6 electron densities with 2 densities being lone pairs and the other 4 being atoms with electrons. Lone pairs have the most repulsion and electrons want to be as far away as possible, so the preferred shape would be square planar with bond angles of 90 or less.
