Final answer:
The hybrid orbitals used by sulfur in SCl₂ are sp³ hybrid orbitals. Sulfur uses an sp³d hybridization to accommodate the ligands and lone pairs in the SCl₂ molecule.
Step-by-step explanation:
The name of the hybrid orbitals used by sulfur in SCl2 is sp3. In this molecule, sulfur has a valence electron configuration of 3s23p4, meaning it has six valence electrons. To accommodate two chloride ligands and two lone pairs, sulfur must expand its octet by utilizing both the s and p orbitals as well as one of the d orbitals. This results in four sp3d hybrid orbitals of equal energy that will be occupied by the lone pairs and used to form bonds with the two chlorine atoms. Thus, the hybridization for sulfur in SCl2 is best represented as sp3d, written in condensed form as sp3d.
