Note. It shows that the phosphorus is in the center with the lone pair of electrons. It is prominent that all the bond angles in trigonal bipyramidal geometry are not identical. Each of these bonds between P and Cl makes 3 90 degrees and 180 degrees bond angles with the supplementary bonds. This concept states that orbitals of atoms that have equal or similar energy can fuse with each other thereby giving rise to new, degenerate orbitals, hybrid in nature. There are five pairs of bonded electrons, out of which three lie on the equatorial plane. It is important to be able to predict and understand the molecular structure of a molecule because many of the properties of a substance are determined by its geometry. The second type of bond is the axial bond. It also has few more uses in the industry as mentioned below: The physical and reactive properties of PCl5 and its industry-wide uses can be well understood through the concepts of Lewis Structure, Molecular Geometry, Hybridization, and Molecular Orbital theory.
