The chemical formula SCl2 represents Sulfur Dichloride. It is the simplest type of Sulfur Chloride and exists as a cherry-red liquid at room temperature. That is acquired via chlorination of S2Cl2 whose impure existence is then distilled making use of PCl3 to offer pure Sulfur Dichloride. That is a corrosive agent and is hazardous come the environment. SCl2 reacts through alkenes and ethylene to type organic thioether (sulfide) compounds. One instance is the danger Sulfur Mustard used in chemistry warfare. The properties of SCl2 room as follows:

SCl2 Valence Electrons

Sulfur is in group 6(Chalcogens) the the periodic table through the digital configuration 3s²3p⁴. Therefore, the Sulfur atom contributes 6 x 1 = 6 valence electrons being in team 7 of the regular table, Chlorine has actually seven valence electrons v a valency the -1. Chlorine’s digital configuration is offered by 3s23p5. The opportunity of electron in its d shell makes 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 given by: 6 + 14 = 20 valence electrons.

SCl2 Lewis Structure

Sulfur is the the very least electronegative and therefore, is placed in the facility of the bones structure. We then heat up the two Chlorine atoms on either side of the Sulfur atom. We will now begin placing the 20 valence electrons accessible to us in accordance through the octet rule.

The electron are an initial placed in in between the atom to kind a covalent bond in between Sulfur and also the 2 Chlorine atoms as presented in the figure.

The staying valence electrons room filled in the outermost atoms, gradually moving inward. We location 6 electrons on every of the 2 Chlorine atoms as presented in the figure.


This leaves united state with 4 remaining valence electrons. These electrons are inserted as lone bag on the Sulfur atom in the center of the molecule as presented in the figure. Therefore, the last Lewis framework of the SCl2 molecule is provided below:


It deserve to be seen in the figure above that the octet dominance is to solve completely. This provides the above Lewis structure completely stable.

SCl2 Hybridization

Sulfur Dichloride comprises two Chlorine atom separated by a lone Sulfur atom. This Sulfur atom forms two covalent bonds through each the the Chlorine atoms. The fulfillment that the octet preeminence on each of the Chlorine atoms leaves 4 valence electrons. These act as lone pairs and also attach us on opposite end of the Sulfur atom. This provides us 4 electron domains- 2 covalent bonds and also two lone pairs. Therefore, the hybridization that the molecule is sp3.

SCl2 shortcut Angles

According to the VSEPR theory, the Chlorine atoms and also the lone pairs repel each other. This offers SCl2 a bond edge of 103°.


SCl2 molecular Geometry and Shape

As checked out in the Lewis framework above, the Chlorine atom repel every other. This gives us a linear shape initially. However, ~ above the enhancement of the 2 lone bag on Sulfur, the molecule geometry i do not care bent. This is in accordance through the VSEPR theory.


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

Concluding Remarks

Let’s quickly summarize the salient functions of SCl2

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