Here's why:

* Sulfur's electron configuration: Sulfur has 6 valence electrons (3s² 3p⁴).

* Bonding in SCl₂: Sulfur forms two single bonds with two chlorine atoms.

* Hybridization: To accommodate the two bonding pairs and two lone pairs of electrons around sulfur, it undergoes sp³ hybridization. This creates four equivalent sp³ hybrid orbitals, with two holding the lone pairs and the other two overlapping with the chlorine orbitals to form the S-Cl bonds.
