The central sulfur atom forms four bonds with the neighboring fluorine atoms and has one lone pair of electrons. However, upon the addition of the two lone pairs on Sulfur, the molecular geometry becomes bent. SnCl2 acts as reducing agent because - Sn4+ is more stable than Sn2+. bonding pairs = 4. nonbonding pairs =0. we can calculate for the steric number (SN) to determine the molecular geometry: SN = m + n where m is the number of bonds and n is the number of non-bonding electron pairs. The reason for this fact is the presence of highly negative halogen fluorine. It causes the formation of partial covalent character in an ionic bond.
