We’re asked to (a) explain the distortion from the ideal square pyramidal structure of TeF5- from 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.
The structure of TeF 5- is
Draw a complete Lewis structure for TeF 5-, and explain the distortion from the ideal square pyramidal structure. (See Exercise 26.)
Two variations of the octahedral geometry (see Table 4‑1) are illustrated below.
Which of the compounds/ions Br3-, ClF3, XeF4, SF4, PF5, ClF5, and SF6 have these molecular structures?
