ICl4-, XeF4 and I3 - all are planar molecule/ ion. Explain
Dear Student,
ICl4-, XeF4 has sp3d2 hybridisation and should have octahedral shape, but due to the presence two of lone pair, there occurs lone pair-lone pair repulsion which distorts its shape to square planar. Therefore. ICl4- and XeF4 are square planar in shape.
I3- has sp3d hybridisation and should have triagonal bipyramidal geometry, but has 3 lone pairs and so there also occurs lone pair-lone pair repulsion which distorts is shape to linear geometry.
Hence. all the three are planar due to the repulsion of lone pairs.
