We’re asked to (a) explain the distortion from the ideal square pyramidal structure of TeF5from its Lewis structure and to (b) determine which of the compounds/ions Br3-, ClF3, XeF4, SF4, PF5, ClF5, and SF6 have similar (square planar or square pyramidal) molecular structures/shape. 


The possible molecular shapes are:



To do so, we first need to draw a Lewis structure for each molecule/ion.  For this, we need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the shape of the molecule.
