Answer:
d. sp3d hybrid orbitals in XeOF4.
Explanation:
In XeOF4, xenon is bonded to one oxygen atom (O) and four fluorine atoms (F). The central xenon atom has an expanded octet, meaning it utilizes hybrid orbitals beyond the typical sp3 hybridization.
The oxygen atom contributes two electron pairs, while each fluorine atom contributes one electron pair. In order to accommodate these electron pairs and form bonds, xenon undergoes sp3d hybridization, resulting in five hybrid orbitals.
