Expert Answer
In figure (a), the lone pair of electrons is present at the axial position so there are three lone pair-bond pair repulsions at 90o. In the figure(b), the lone pair of electrons is present at the equatorial position and there are two lone pair- bond pair repulsions. Hence figure (b) is more stable as compared to figure (a). The shape shown in figure (b) is distorted tetrahedron, a folded square or a see saw.
