Trigonal bipyramidal molecular geometry - Wikipedia
Axial (or apical) and equatorial positions. Trigonal bipyramidal molecular shape. ax = axial ligand (on unique axis) eq = equatorial ligand (in plane perpendicular to unique axis) The five atoms bonded to the central atom are not all equivalent, and two different types of position are defined.

With three lone pairs about the central atom, we can arrange the two F atoms in three possible ways: both F atoms can be axial, one can be axial and one equatorial, or both can be equatorial:
4.6: Axial and Equatorial Bonds in Cyclohexane
Each carbon has an axial and an equatorial bond. Each face of the cyclohexane ring has three axial and three equatorial bonds. Each face alternates between axial and equatorial bonds. Then looking at the "up" bond on each carbon in the cyclohexane ring they will alternate axial-equatorial-axial ect. When looking down at a cyclohexane ring:
VSEPR Theory & Chart - ChemTalk
Each P-F bond uses 2 valence electrons and each fluorine atom has three lone pairs. Phosphorus can expand its octet. Three of the fluorine atoms are in what is called the equatorial position. The other two are in what is called the axial position.
48 Predicting Molecular Shapes: VSEPR Model (M9Q1) - Unizin
Introduction. This section explores how we predict the molecular and electron-pair shapes of molecules using the VSEPR (Valence Shell Electron Pair Repulsion) theory. We will first go over what VSEPR theory is and how it defines an electron-pair geometry and a molecular geometry.
5.2: Molecular Shape - Chemistry LibreTexts
Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure.
VSEPR Theory - Chemistry Steps
Molecular Geometry. VSEPR Theory. The VSEPR (valence shell electron pair repulsion) theory predicts the geometry of atoms or molecules. It is based on the principle that atoms and lone pairs repel each other because of electrostatic forces and thus, they are positioned as far away as possible to give the molecule an optimal geometry.
Molecular Geometry — Shapes & Examples - Expii
When the bonding atoms are directly above or below the central atom, we call them axial. When the atoms distribute around the center plane of the molecule, we call them equatorial. Many of the molecular geometries are combinations of axial and equatorial positions. However, some have bonds that angle away because of electrostatic interactions.

Introduction. In XY 5 trigonal bipyramidal molecules with D 3h symmetry (PF 5, VF 5, Fe (CO) 5, etc), the mechanism of the exchange of the axial and equatorial terminal groups has been the source of great interest for some fifty years now, making its way into many textbooks, but not entirely without pedagogic confusion.
Molecular Geometry - Oklahoma State University–Stillwater
The term electron-pair geometry is the name of the geometry of the electron-pair/groups/domains on the central atom, whether they are bonding or non-bonding. Molecular geometry is the name of the geometry used to describe the shape of a molecule.
