Detailed Solution

Since the ICl4 ion includes four bond pairs in addition to lone pairs, it takes the shape of a square planar molecular structure. It has octahedral geometry.
Since not all of its atoms reside in the same plane, TeCl4 is not a planar substance.
The bond pairs occupy the equatorial plane and the axial plane. Therefore, we can say that the plane in which the bond pairs are present is planar.
