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.
Consider the polyatomic ion PCl 4- and its three dimensional structure. What is the electronic geometry and the molecular geometry for this ion?
1. tetrahedral; tetrahedral
2. trigonal bypyramidal; tetrahedral
3. octahedral; square planar
4. octahedral; square pyramidal
5. trigonal bipyramidal; T-shaped
6. trigonal bipyramidal; seesaw
