Carbon disulfide or CS2 is one of the very common molecules we come across while researching chemistry.

You are watching: In carbon disulfide, how many lone pairs of electrons are on each sulfur atom?

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

Now let us learn around this sulfide in a in-depth manner.

Carbon disulfide (CS2) is a flammable, and also highly odorous( no tolerable) molecule in fluid form.

It is generally colorless and volatile that can cause a most poisonous outcomes.

From liver and kidney conditions to weight loss and vision impairment, exposure come CS2 is not desirable.

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

It have the right to be offered for the manufacturing of viscose rayon and also cellophane.

It is likewise utilized together pesticides and adhesives.

Now let us move below to deeply research the principles like lewis structure, molecule geometry, hybridization of the CS2 molecule.

Lewis framework of CS2

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

Lewis Structure is just one of the crucial terminologies to know the chemical bonding of a molecule since it represents the molecular structure.

It depends on the octet dominion concept and also is an extension of the electron period diagram.

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

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

(A valence electron is a name provided to the external shell electron of one atom that takes component in the development of a chemistry bond).

A very important point to be provided here is the function of the indicators ‘+’ and ‘-’. If the optimistic ‘+’ sign suggests the lose of electron i.e lose of an unfavorable charge, the negative ‘-’ authorize is to signify the get of electrons.

Step 2: The second step is based on finding the central atom that the molecule.

Usually, the one through the greatest valence i.e. Bonding web page ( in other words, the very least electronegative) is the central atom.

We can determine the electronegativity worth by browsing through the routine table. As per the trend, the is likely to decrease under a group.

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

Step 4: Next, our task is to complete the octet of the atoms around each the the outer ones with the staying 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 inspect whether there space bonds left to it is in formed.

If there is a need of multiple link formation, we need to create twin or triple bonds together per requirements to accomplish the octet rule.

Step 6: The final step that Lewis diagram formation is come verify whether all the atoms are in their lowest possible formal charge.

(A officially charge, also abbreviated as FC is the fee that is assigned come an atom that a molecule as soon as we assume that chemical binding are constantly shared equally between atoms within a molecule.)

Here is exactly how we can conveniently calculate the official charge:


Let us understand see how we can draw the Lewis framework for CS2

1. Carbon belonging to team 4 the the routine table.

Therefore, the variety of valence electrons in the Carbon atom =4.

Sulfur(S) belong to group 6 has 6 valence electrons.

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

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

2. Follow to step 2, carbon is the the very least electronegative having actually the greatest bonding sites. C is the main atom here.

3. The skeleton diagram of CS2 is attracted below.


4. We can check and also find out that both the sulfur atoms have fulfilled their octet dominion here. But, carbon is the only one left with only four electrons surrounding it.

We can quickly mend this issue by share the electrons about sulfur and bringing them together carbon, therefore 2 valence electron from every sulfur atom in the direction of carbon will deal with the problem here.

5. We room therefore an altering the lone pairs into dual bonds together per necessity.

6. Now, we need to inspect the formal charge adhering to the offered mentioned formula.

This is exactly how we attract a complete Lewis structure of Carbon disulfide.

Hybridization of CS2

Carbon disulfide has sp hybridization.

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

This procedure of hybridization is just one of the crucial concepts the bonding and can be explained in two various methods- one with the help of theory and the various other one relying on formulae.


Let us an initial make friend go through the theoretical standpoint to make things easier!

An ‘s’ orbital will overlap with a ‘p’ orbit to create sp hybridization.

If a central atom( right here C) has two valence electron thickness regions surrounding it, climate it exhibits sp hybridization.

C ground state configuration: 1s2 2s2 2p2

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

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

The electron of 2s and also 2p orbitals of C form the double bonds and also thus they result in sp hybridization.

Here is a formula that can calculate the hybridization value


Here, H: hybridization value

M: valence electron no.

C: charge of the cations

A: fee of the anions

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

Also, we have the right to calculate the steric number.

Steric Number= No that sigma bonds + No of pi lone pairs( of the main atom, below Carbon).

The octet has actually been fulfilled through the help of sharing valence electrons amongst the two sulfur and the carbon atoms, as such here over there is no lone pair.

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

Molecular Geometry of CS2

As discussed earlier, CS2 has a direct shape. Here, the link angles type an edge of 180 degrees.

To determine the molecule geometry the a molecule, we should get acquainted with a principle called VSEPR theory.Now, what is the VSEPR theory?

VSEPR concept is the short type for Valence covering Electron Pair Repulsion Theory.

It is based on the minimum repulsion concept where valence electron pairs the repel each various other will kind the arrangement or framework that will justify the the very least repulsion.

Below is the chart the you have the right to refer to uncover the geometry of different types of molecules.


When any type of compound has a formula similar to the generic one AX2, it means that X is the bonded atom, and also the molecule will have actually 0 lone pairs and 2 shortcut pairs.

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


Polarity the CS2

Before we comment on whether CS2 is polar or non-polar, let us just check a concise an interpretation of polarity.

Polarity is basically defined as the problem of having actually both confident and negative charges i.e. That denotes the distribution of electric charges throughout the atoms or molecule of a compound.

A polar molecule will an outcome due come unequal sharing of electron whereas non-polar ones are neutral.

Now, coming to the carbon de defiders structure, we currently are accustomed to the diagrammatical representation of the molecule.

From there, we have the right to decipher the it is a direct molecule, thus the valence electrons approximately sulfur and carbon space spread equally with no sulfur having a higher influence on carbon 보다 the other one.

Since over there is no pole, for this reason CS2 is non-polar.

For the thorough reasons the the polarity that CS2, girlfriend can likewise refer to the polarity of CS2.

Also, girlfriend must inspect out the post written ~ above the covalent nature of CS2.


Understanding of any type of molecule needs a deep knowledge intake of the internal chemistry and bonding structure.
