The Trigonal Bipyramidal Molecular Geometry happens when the central atom is connected to five atoms forming five bonds and no lone pairs. This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push away from) each other in three dimensional space and this gives the molecules their shape. and and trigonal pyramid the molecular geometry. A trigonal bipyramidal electronic geometry and seesaw molecular geometry is possible if the central atom contains five areas of electron density, one of which is a lone pair.
