If girlfriend have ever come across the formation of carbon tetrachloride, a well-known reaction while researching chlorine, you have actually heard about CS2.

Now let united state learn about this sulfide in a detailed manner.

Carbon de defiders (CS2) is a flammable, and also highly odorous( no tolerable) molecule in liquid form.

It is generally colorless and also volatile that can cause a lot of poisonous outcomes.

From liver and also kidney diseases to load loss and also vision impairment, exposure come CS2 is no desirable.

Used as a solvent for iodine and phosphorus, it has actually a boiling allude of 46.24 0C and a thickness of 1.539 g/cc.

It deserve to be used for the production of viscose rayon and also cellophane.

It is additionally utilized together pesticides and also adhesives.

Now let united state move listed below to deeply research the ideas like lewis structure, molecular geometry, hybridization that the CS2 molecule.

Lewis framework of CS2

If you space a college student of chemistry, the is nearly obvious that you are conscious of the ax ‘Lewis Structure”. If not, here’s a quick explanation that the above-mentioned topic.

Lewis Structure is just one of the vital terminologies to recognize the chemical bonding of a molecule because it represents the molecular structure.

It depends on the octet rule concept and also is an extension of the electron dot diagram.

Thus, to have a considerable idea around CS2 Lewis Structure, let united state go v each step plainly and systematically.

Step 1: The very an initial step towards drawing the structure of a molecule is come decipher the total variety of valence electrons.

(A valence electron is a name given to the external shell electron of one atom that takes part in the development of a chemical bond).

A very important point to be listed here is the role of the indications ‘+’ and ‘-’. If the optimistic ‘+’ sign shows the lose of electrons i.e ns of an unfavorable charge, the negative ‘-’ authorize is to denote the obtain of electrons.

Step 2: The second step is based upon finding the main atom that the molecule.

Usually, the one through the highest possible valence i.e. Bonding sites ( in other words, least electronegative) is the main atom.

We deserve to determine the electronegativity worth by looking through the regular table. As per the trend, it is most likely to decrease down a group.

Step 3: Now, we require to attract a skeleton diagram having the presence of solitary bonds.

Step 4: Next, our task is to complete the octet of the atoms roughly each that the external ones with the continuing to be electrons.

The advisable decision is to end up the electronegative ones very first before starting with the electropositive atoms.

Step 5: In this step, we have actually to check whether there space bonds left to be formed.

If there is a necessity of multiple shortcut formation, we need to create double or triple bonds together per demands to satisfy the octet rule.

Step 6: The last step that Lewis diagram formation is come verify whether all the atoms space in your lowest possible formal charge.

(A formal charge, also abbreviated together FC is the fee that is assigned come an atom of a molecule once we assume that chemical bond are constantly shared equally in between atoms inside a molecule.)

Here is exactly how we can quickly calculate the formal charge:


Let us understand see exactly how we can attract the Lewis structure for CS2

1. Carbon belonging to team 4 that the periodic table.

Therefore, the number of valence electron in the Carbon atom =4.

Sulfur(S) belong to team 6 has actually 6 valence electrons.

CS2 has actually two S atoms, hence, the valence electron in sulfur here are 6*2=12.

Total valence electron is CS2 = 12+4 = 16.

2. According to action 2, carbon is the least electronegative having actually the highest possible bonding sites. C is the main atom here.

3. The skeleton chart of CS2 is drawn below.


4. We can check and also find out that both the sulfur atoms have fulfilled your octet preeminence here. But, carbon is the just one left with only 4 electrons bordering it.

We can conveniently mend this concern by share the electrons roughly sulfur and bringing them together carbon, for this reason 2 valence electron from every sulfur atom towards carbon will settle the difficulty here.

5. We are therefore changing the lone bag into twin bonds together per necessity.

6. Now, we need to check the official charge adhering to the given mentioned formula.

This is just how we draw a finish Lewis framework of Carbon disulfide.

Hybridization that CS2

Carbon disulfide has actually sp hybridization.

Now, what is hybridization? perform you know that atoms use hybrid orbitals and not atom orbitals to form chemical binding in a molecule?

This process of hybridization is among the an important concepts that bonding and also can be defined in two various methods- one v the help of theory and also the various other one relying on formulae.


Let us first make you go v the theoretical standpoint to make things easier!

An ‘s’ orbital will overlap through a ‘p’ orbital to develop sp hybridization.

If a main atom( below C) has actually two valence electron thickness regions bordering it, then it exhibits sp hybridization.

C ground state configuration: 1s2 2s2 2p2

S soil state configuration: 1s2 2s2 2p6 3s2 3p4

Just in the over section, while discussing the Lewis structure we learned that in CS2 two double bonds are formed and also eight of the 16 valence electrons are offered up because that this purpose.

The electrons of 2s and also 2p orbitals that C form the dual bonds and also thus they result in sp hybridization.

Here is a formula that have the right to calculate the hybridization value


Here, H: hybridization value

M: valence electron no.

C: fee of the cations

A: fee of the anions

Therefore, H=2 here. The signifies the the hybridization kind is sp.

Also, we deserve to calculate the steric number.

Steric Number= No the sigma bond + No that pi lone pairs( that the central atom, below Carbon).

The octet has been fulfilled by the aid of sharing valence electrons amongst the 2 sulfur and the carbon atoms, therefore here over there is no lone pair.

There space two sigma bond formed, for this reason steric number=2, sp hybridization.

Molecular Geometry that CS2

As disputed earlier, CS2 has actually a straight shape. Here, the shortcut angles type an edge of 180 degrees.

To recognize the molecular geometry the a molecule, we must get familiar with a concept called VSEPR theory.Now, what is the VSEPR theory?

VSEPR theory is the short form for Valence shell Electron Pair Repulsion Theory.

It is based upon the minimum repulsion ide where valence electron pairs that repel each other will form the arrangement or structure that will justify the least repulsion.

Below is the chart the you can refer to discover the geometry that different types of molecules.


When any type of compound has actually a formula comparable to the share one AX2, it way that X is the external inspection atom, and also the molecule will have actually 0 lone pairs and 2 shortcut pairs.

Thus, in the case of CS2, Sulfur is the bonded atom.


Polarity that CS2

Before we talk about whether CS2 is polar or non-polar, let united state just check a concise meaning of polarity.

Polarity is basically defined as the condition of having both positive and an adverse charges i.e. It denotes the circulation of electric charges throughout the atoms or molecules of a compound.

A polar molecule will result due come unequal share of electrons whereas non-polar ones room neutral.

Now, coming to the carbon disulfide structure, we already are accustomed come the diagrammatical representation of the molecule.

From there, we have the right to decipher the it is a direct molecule, therefore the valence electrons roughly sulfur and also carbon room spread equally with no sulfur having actually a higher influence ~ above carbon than the other one.

Since there is no pole, therefore CS2 is non-polar.

For the comprehensive reasons the the polarity that CS2, girlfriend can additionally refer come the polarity the CS2.

Also, friend must check out the post written top top the covalent nature of CS2.


Understanding of any molecule needs a deep expertise intake that the internal chemistry and bonding structure.
