We’re being asked to determine the electron pair and molecular geometry of CO32–.
The possible electron pair and molecular geometries are:
To do so, we first need to draw a Lewis structure for CO32–.
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.
Determine the electron geometry (eg) and molecular geometry (mg) of CO32-
a) eg-tetrahedral, mg = tetrahedral
b) es-tetrahedral, mg = trigonal pyramidal
c) eg = trigonal planar, mg = bent
d) eg = trigonal planar, mg = trigonal planar
e) eg = tetrahedral, mg = trigonal planar
