What is the hybridization of the central atom in the molecule IF5?
Correct: B
The molecule IF5 has a trigonal bipyramidal geometry. To determine the hybridization of the central atom, we need to look at the number of electron domains around the central atom. In this case, there are five electron domains (five bonding pairs and one lone pair). The hybridization that corresponds to five electron domains is sp3d. Therefore, the correct answer is sp3d.
