A.
Name of the (XeF5)- is Xenon pentafluoride anion.
This molecule is having seven pairs of electrons. Among them, five pairs are bonding pairs forms Xe-F bonds and two pairs are lone pairs of electrons which not involving in the bonding.
We know from VSEPR theory, the structure of the molecule can determined by differences of electrostatic repulsion between bonding pairs and lone pairs involves in the molecule.
We know that, the order of repulsion is lone pair-lone pair>lone pair-bond pair>bond pair-bond pair.
Because, lone pairs are average closer to nucleus than bonding pair and more strongly repulse other electrons.
The structure of the (XeF5)- is pentagonal bipyramidal shape which is consider as parent shape with all seven pairs of electrons.
The two pairs of lone pair of electrons are kept in equatorial plane to reduce the repulsion of lone pair-lone pair electrons. As a result, the shape of the molecule is pentagonal planar.

INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...
