Sulfur hexafluoride (SF6) has sp3d2 hybridization because of its central sulfur atom's coordination number of 6. In order to accommodate this coordination number, the sulfur atom undergoes hybridization involving one 3s orbital, three 3p orbitals, and two 3d orbitals, resulting in sp3d2 hybridization. This allows the sulfur atom to form six bonding pairs with the surrounding fluorine atoms, creating a stable octahedral geometry.
An example of sp3d2 hybridization is in the molecule IF7 (Iodine heptachloride). In this molecule, the iodine atom undergoes sp3d2 hybridization where one 5s, three 5p, and two 5d orbitals combine to form six equivalent sp3d2 hybrid orbitals.
Two of the molecules listed, IF5 and AsCl5, have sp3d2 hybridization on the central atom. SeCl6 and XeCl4 have sp3d3 hybridization.
The hybridization of arsenic in AsF5 is sp3d2 hybridization, where arsenic forms five equivalent sp3d2 hybrid orbitals. In AsF3, the hybridization is sp3, with arsenic forming three sp3 hybrid orbitals.
The hybridization of the central atom (Cl) in ClF5 is sp3d2. This means that the 3d, 4s, and three 4p orbitals of chlorine hybridize to form six equivalent sp3d2 orbitals, allowing for the five bonding pairs of electrons in the molecule.
The central atom in Sif6 2- is silicon (Si). To determine the hybridization, we count the number of regions of electron density around the silicon atom, which in this case is six. Therefore, the hybridization of Si in Sif6 2- is sp3d2.

Since the central sulfur has six atoms bound to it, it is sp3d2
The bromine atom in BrF5 has sp3d2 hybridization. This means that it has one 3s, three 3p, and two 3d orbitals that combine to form six equivalent sp3d2 hybrid orbitals.
The central atom in SIF6^2- is sulfur. The sulfur atom in SIF6^2- has an sp3d2 hybridization, which includes one s orbital, three p orbitals, and two d orbitals to form six sp3d2 hybrid orbitals around the sulfur atom.
Good question. A lot of people use them interchangeably, and assume they are the same. They are not the same. With sp3d2, the s, p and d orbitals which are hybridized all come from the same energy level, for instance, it has been taught that when sulfur combines with six fluorine atoms to make SF6 that the 3s, 3p and two 3d orbitals hybridize to make the sp3d2 hybrid orbital set. But d2sp3 is different. In this case the d-orbitals come from the n-1 energy level. Transition metals may exhibit d2sp3 hybridization where the d orbitals are from the 3d and the s and p orbitals are the 4s and 3d. The bottom line is this, in sp3d2 hybridization all of the orbitals have the same principal quantum number. In d2sp3, the principle quantum number of the d orbitals is one less than the principal quantum numbers of the s and p orbitals. We see d2sp3 hybridization in the transitions metals and sp3d2 hybridization in the nonmetals. There is one more issue. Chemists today are finding out that in compounds like SF6 there is no involvement of d-orbitals. In other words, there is no sp3d2 hybridization in SF6. A more likely explanation involves what is called "3-center, 4-electron" bonding in which three orbitals overlap axially (in a straight line) and contain a total of 4 electrons. This means that the 3 unhybridized p-orbitals of sulfur are all that is needed to make the six bonds with fluorine atoms. Now you can be the first in your class to point out that there really isn't any sp3d2 hybridization at all.
The hybridization of each central atom in the order from a to e is sp3, sp2, sp3d, sp3d2, and sp3d3.
