Identify the hybridization of all interior atoms for the molecules S2Cl2 and SF4, according to valence bond theory, in the diagram showing orbital overlap below.
The Correct Answer and Explanation is :
To address the question about the hybridization of interior atoms in S₂Cl₂ and SF₄, according to Valence Bond Theory, let’s break it down for each molecule:
S₂Cl₂ (Disulfur dichloride):
- Sulfur (S) Atom Hybridization:
- In S₂Cl₂, each sulfur atom forms two single bonds with chlorine atoms, and one lone pair of electrons remains on each sulfur.
- Since sulfur has two bonding regions (two bonds to chlorine) and one lone pair, the sulfur atoms will have an sp³ hybridization. This is because sulfur undergoes hybridization to form four equivalent hybrid orbitals. Two of these orbitals form sigma bonds with chlorine atoms, and the remaining two orbitals accommodate the lone pair and another bonding region, although in this case, only bonding with chlorine is considered.
- Chlorine (Cl) Atom Hybridization:
- Each chlorine atom in S₂Cl₂ forms a single bond with sulfur. Chlorine atoms also have three lone pairs. As chlorine typically forms a single bond and has three lone pairs, the Cl atoms will have an sp³ hybridization.
SF₄ (Sulfur tetrafluoride):
- Sulfur (S) Atom Hybridization:
- In SF₄, sulfur is the central atom, forming four bonds with fluorine atoms and having one lone pair of electrons.
- To accommodate the four bonding pairs and one lone pair, the sulfur atom undergoes sp³d hybridization. The sp³d hybridization suggests that the sulfur atom uses one s orbital, three p orbitals, and one d orbital to form five hybrid orbitals. Four of these hybrid orbitals form sigma bonds with fluorine atoms, and the remaining orbital contains the lone pair of electrons.
- Fluorine (F) Atom Hybridization:
- Each fluorine atom in SF₄ forms a single bond with sulfur and retains three lone pairs. The hybridization of fluorine in SF₄ is sp³ hybridized, similar to the chlorine atoms in S₂Cl₂, as they only participate in single bonds and have lone pairs.
In summary:
- S₂Cl₂: Sulfur atoms are sp³ hybridized; Chlorine atoms are sp³ hybridized.
- SF₄: Sulfur atom is sp³d hybridized; Fluorine atoms are sp³ hybridized.
