Vedclass · Answer

(C) The $VSEPR$ theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.Let's try to understand with the example of $PF_5$.Repulsion between the five pairs of valence electrons on the phosphorus atom in $PF_5$ can be minimized by distributing these electrons toward the corners of a trigonal bipyramid.Three of the positions in a trigonal bipyramid are labeled equatorial because they lie along the equator of the molecule.The other two are axial because they lie along an axis perpendicular to the equatorial plane.The angle between the three equatorial positions is $120^{\circ}$ while the angle between an axial and an equatorial position is $90^{\circ}$.
