Determine the electron geometry (eg), molecular geometry(mg) and polarity of XeO 3.

a. eg = tetrahedral, mg = trigonal pyramidal, polar

b. eg = trigonal bipyramidal, mg = trigonal planar, nonpolar

c. eg = trigonal planar, mg = trigonal pyramidal, polar

d. eg = trigonal planar, mg = trigonal planar, nonpolar

e. eg = octahedral, mg = tetrahedral, nonpolar


We’re being asked to determine the electron and molecular geometry and polarity of XeO3. The possible molecular geometries and electron geometries are:

To do so, we first need to draw a Lewis structure for XeO­3

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: Draw the dipoles and analyze the polarity

Step 5:  Determine the electron geometry of the molecule.

Step 6:  Determine the molecular geometry of the molecule.
