The equatorial pair of ligands is situated in a plane orthogonal to the axis of the axial pair. If there are 3 X atoms and 2 Y atoms, then one Y atom could be placed in a equatorial position and the other in an axial position, or both Y atoms could be placed in the same position. For the seesaw, tetrahedral, and square pyramidal geometries, we are to rank these in order of increasing bond angles for the smallest bond angle for each geometry. Molecular geometries (linear, trigonal, tetrahedral, trigonal bipyramidal, and octahedral) are determined by the VSEPR theory. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. If the central atom has lone pairs, then there exists a repulsion from the lone pairs to the bonds, causing the bond angle to shrink a little bit. STUDY.
