We’re being asked to determine the electron pair and molecular geometry of PCl4

The possible electron pair and molecular geometries are: To do so, we first need to draw a Lewis structure for PCl4

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 electron pair geometry of the molecule.

Step 5: Determine the molecular geometry of the molecule.
