The correct answer to this question is Square planar. It describes the stereochemistry of a chemical compound, which they adopt. The bond angle is 90 degrees, and the polarity is zero. It can be achieved when a pair of ligands are removed from the z-axis. This z-axis is on the octahedron.

This removal leaves four ligands. Other examples are PtCI42- and XeF4 (xenon tetrafluoride). XeF4 has six hybrid orbitals that are equally spaced at 90 degrees angles. The coordination number of square planar is 4. Square planar differ from tetrahedral. This question would be found on chemistry tests for students studying that subject.

Different atoms have different configurations depending on the shell of electrons surrounding them. When these atoms come together in different forms to form molecules, they give rise to different molecular configurations as well. Among the different configuration, BrF4 is a molecular structure consisting of bromine and fluorine.

The molecular geometry of this molecule is square planar as this how the different lone pairs of both atoms adjust with one another. The four fluorine atoms occupy different positions around bromine giving it a planar shape while occupying four corners. Hence, the ultimate geometry is named the square planar shape of BrF4.
