Axial and Equatorial Positions in Molecular Geometry

In molecular geometry, the axial and equatorial positions refer to the positions of atoms or groups of atoms relative to a central atom. Axial positions are those that lie along the axis of symmetry of a molecule, while equatorial positions are those that lie in the plane perpendicular to the axis of symmetry.

Trigonal Bipyramidal and Pentagonal Bipyramidal Geometry

Trigonal bipyramidal and pentagonal bipyramidal geometry are two types of molecular geometry that involve five atoms or groups of atoms arranged around a central atom. In trigonal bipyramidal geometry, the central atom is surrounded by three atoms or groups of atoms in a trigonal plane, and two more atoms or groups of atoms in axial positions perpendicular to the plane. In pentagonal bipyramidal geometry, there are five atoms or groups of atoms in a pentagonal plane, and two more atoms or groups of atoms in axial positions perpendicular to the plane.

Presence of Axial and Equatorial Positions

In order for both axial and equatorial positions to be present in a molecular geometry, the geometry must have five atoms or groups of atoms arranged around a central atom, with some of them in a trigonal plane and others in axial positions perpendicular to the plane. The only set of geometry that meets this criteria is trigonal bipyramidal and pentagonal bipyramidal geometry, as both of these involve five atoms or groups of atoms arranged around a central atom with two in axial positions perpendicular to the plane.

Therefore, the correct answer is option C, Trigonal bipyramidal and pentagonal bipyramidal.
