검증된 단계별 안내1
Identify the central atom and its valence electrons. In SCl_2, sulfur (S) is the central atom with 6 valence electrons.
Determine the number of bonded atoms and lone pairs on sulfur. Sulfur is bonded to 2 chlorine atoms and has 2 lone pairs of electrons.
Calculate the steric number, which is the sum of bonded atoms and lone pairs: Steric number = 2 (bonded atoms) + 2 (lone pairs) = 4.
Use the steric number to determine the hybridization. A steric number of 4 corresponds to sp^3 hybridization.
Conclude that sulfur in SCl_2 uses sp^3 hybrid orbitals to accommodate the bonding and lone pairs.
