**Unformatted text preview: **atoms. The new shape is then renamed based on the shape of the atoms. Remember, once you have estabilished the correct electronic geometry, the molecular geometry MUST be either the same as the electronic or one of the shapes listed directly under the electronic geometry. In other words, each shape in a given column here has the same electronic geometry given at the top of the column. Polarity If all the positions on the electronic geometry are the same (have the same atoms surrounding the central atom), the molecule is NOT polar because of the symmetry. Any of the other molecular geometries (except square planar and linear) under the box will be polar. sp sp 2 sp 3 d sp 3 sp 3 d 2 McCord 10/2005 note that the lone pairs all go in the equatorial positions AX 2 AX 3 AX 4 AX 5 AX 6 AX 2 E AX 3 E AX 2 E 2 AX 4 E AX 5 E AX 3 E 2 AX 4 E 2 AX 2 E 3 AX 3 E 3 AX 2 E 4...
