Final answer:
The expected hybridization of the central atom in a tetrahedral molecule of Til4 is sp³d².
Step-by-step explanation:
The expected hybridization of the central atom in a molecule of Til4, which is tetrahedral, is sp³d². In order to determine the hybridization, we need to consider the steric number of the central atom, which in this case is 4. The steric number indicates the number of regions of electron density around the central atom. For a tetrahedral molecule, the steric number is 4, corresponding to the possible hybridization of sp³d².
