Square planar vs Tetrahedral

Postby MichelleTran3I » Tue Nov 28, 2017 11:20 pm

How can you differentiate between a square planar shape and a tetrahedral shape when looking at Lewis dot structures? Thanks!

A square planar shape has six areas of electron density, 2 of which are lone pairs, whereas a tetrahedal shape has four areas of electron density and no lone pairs.

A square planar molecule has the molecule notation of AX4E2 where tetrahedral has the molecule notation of AX4. In other words, a square planar molecule has 2 pairs of free electrons.
