Dec 27, 2020 · The correct answer to this question is B, square planar. While IF4- has an octahedral electron geometry, the molecular geometry of IF4- takes on a square planar shape. The cause of this is that iodine carries two lone pairs, with one above the plane on the x-axis and one below the plane on the x-axis. In table salt, sodium chloride, sodium is the cation (Na+) and chloride is the anion (Cl-). In the crystal structure, the anion (Cl-) and the cation (Na+) form a regular pattern alternating back and forth. In the 2 dimensional picture below we can see that each sodium ( Na+ ) is surrounded by chlorides(Cl-).
