i just took a final for chemistry and one of the questions what...draw a stereostructure of PCl5...i had no idea what to do can somebody please tell me?

Sterostructure is its three-dimensional structure in space. The central P atom has 5 bonding pairs and no lone pairs, so the Cl atoms will be arranged in a trigonal bipyramidal shape, with 90 degrees between the axial and equatorial bonds, and 120 degrees between the equatorial bonds themselves.

Sterostructure is a 3D representation of what a molecule would look like. You can figure out the sterostructure based on the Lewis Dot Diagram and VSEPR model. For PCl5, the stereostructure would be trigonal bipyrimidal

Remember that the electronic shape of phosphorus pentachloride is trigonal bipyramidal, so you can arrange your chlorine atoms in either axial or equatorial positions. Try out putting the lone pair (the sixth "ligand") in different locations and see what you get.
