Answer:
The correct option is: C.) Octahedral
Explanation:
Iodine pentafluoride (IF₅) is an inorganic interhalogen compound in which the oxidation state of iodine is +5 and the oxidation state of fluorine is (-1).
In this molecule, iodine is sp³d² hybridized and covalently bonded to five fluorine atoms. So there are 5 bond pair of electrons and 1 lone pair of electron around iodine.
Thus the steric number = 6
According to the VSEPR theory, the electron pair arrangement of a molecule with steric number 6 is octahedral.
Therefore, electron pair arrangement around iodine in IF₅ molecule is octahedral.
