The shape of IF4​ will be:-

a, square planer

b.tetrahedral

c.pyiramidal

1. none

Dear student 

IF4( iodine tetrafluoride ) has an octahedral electron geometry, but the molecular geometry states that the atoms take a square planar shape. This is because iodine carries two lone pairs,  one above and below the plane on the x-axis.
Hence, option A is correct.
