The chemical formula SCl2 to represent Sulfur Dichloride. It is the simplest form of Sulfur Chloride and exists as a cherry-red liquid at room temperature. It is derived via chlorination of S2Cl2 who impure presence is climate distilled using PCl3 to provide pure Sulfur Dichloride. It is a corrosive agent and also is hazardous come the environment. SCl2 reacts v alkenes and ethylene to kind organic thioether (sulfide) compounds. One example is the danger Sulfur Mustard offered in chemistry warfare. The nature of SCl2 space as follows:

SCl2 Valence Electrons

Sulfur is in team 6(Chalcogens) of the periodic table v the digital configuration 3s²3p⁴. Therefore, the Sulfur atom contributes 6 x 1 = 6 valence electrons being in team 7 of the routine table, Chlorine has seven valence electrons through a valency the -1. Chlorine’s electronic configuration is given by 3s23p5. The opportunity of electron in the d shell renders it hypervalent. Therefore, the 2 Chlorine atoms contribute 7 x 2 = 14 valence electrons. Now, the total number of valence electrons accessible in SCl2 is offered by: 6 + 14 = 20 valence electrons.

SCl2 Lewis Structure

Sulfur is the the very least electronegative and also therefore, is put in the facility of the skeleton structure. We then heat up the 2 Chlorine atoms on either next of the Sulfur atom. We will certainly now begin placing the 20 valence electrons accessible to us in accordance with the octet rule.

The electrons are first placed in between the atoms to form a covalent bond between Sulfur and the 2 Chlorine atom as displayed in the figure.

The remaining valence electrons are filled in the outermost atoms, progressively moving inward. We location 6 electrons on each of the two Chlorine atoms as displayed in the figure.


This leaves united state with 4 remaining valence electrons. This electrons are placed as lone pairs on the Sulfur atom in the facility of the molecule as displayed in the figure. Therefore, the final Lewis framework of the SCl2 molecule is provided below:


It can be viewed in the figure over that the octet dominance is solve completely. This makes the above Lewis structure totally stable.

SCl2 Hybridization

Sulfur Dichloride comprises two Chlorine atoms separated by a lone Sulfur atom. This Sulfur atom creates two covalent bonds with each that the Chlorine atoms. The fulfillment that the octet preeminence on every of the Chlorine atoms leaves 4 valence electrons. This act together lone pairs and also attach us on opposite ends of the Sulfur atom. This offers us 4 electron domains- two covalent bonds and two lone pairs. Therefore, the hybridization that the molecule is sp3.

SCl2 bond Angles

According come the VSEPR theory, the Chlorine atoms and the lone bag repel each other. This gives SCl2 a bond edge of 103°.


SCl2 molecular Geometry and also Shape

As viewed in the Lewis structure above, the Chlorine atom repel each other. This offers us a direct shape initially. However, ~ above the addition of the two lone pairs on Sulfur, the molecular geometry i do not care bent. This is in accordance v the VSEPR theory.


Therefore, SCl2 has actually a Bent molecule geometry and also a tetrahedral shape in nature.

Concluding Remarks

Let’s easily summarize the salient attributes of SCl2

SCl2 consists of a solitary Sulfur atom surrounding by two Chlorine atoms.In its many stable state, Sulfur acts together the central atom and also forms 2 covalent bonds with the Chlorine atoms. It additionally possesses 2 lone pairs.Due to the visibility of 4 electron domains and also its steric number being 4, the hybridization the SCl2 is provided by sp3.SCl2 has a bent molecule structure and a tetrahedral digital shape.It has actually bond angles of 103°.
