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

You are watching: What is the lewis structure for cs2

If girlfriend have ever before come across the formation of carbon tetrachloride, a popular reaction while examining 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 highly odorous( no tolerable) molecule in liquid form.

It is typically colorless and volatile the can reason a the majority of poisonous outcomes.

From liver and kidney illness to weight loss and vision impairment, exposure come CS2 is no desirable.

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

It can be supplied for the manufacturing of viscose rayon and also cellophane.

It is likewise utilized together pesticides and adhesives.

Now let united state move below to deeply examine the concepts like lewis structure, molecule geometry, hybridization of the CS2 molecule.

Lewis structure of CS2

If you are a college student of chemistry, it is virtually obvious the you are mindful of the hatchet ‘Lewis Structure”. If not, here’s a quick explanation the the above-mentioned topic.

Lewis Structure is one of the key terminologies to know the chemical bonding of a molecule because it to represent the molecule structure.

It relies on the octet dominance concept and is an extension of the electron dot diagram.

Thus, to have a considerable idea around CS2 Lewis Structure, let us go with each step plainly and systematically.

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

(A valence electron is a name provided to the outer shell electron of one atom that takes component in the creation of a chemical bond).

A very important point to be provided here is the function of the indicators ‘+’ and ‘-’. While the optimistic ‘+’ sign indicates the ns of electron i.e loss of an adverse charge, the an adverse ‘-’ authorize is to represent the get of electrons.

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

Usually, the one through the highest valence i.e. Bonding website ( in various other words, least electronegative) is the central atom.

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

Step 3: Now, we require to draw a skeleton diagram having actually the existence of single bonds.

Step 4: Next, our job is to complete the octet the the atoms about each of the outer ones through the staying electrons.

The advisable decision is to complete the electronegative ones very first before beginning with the electropositive atoms.

Step 5: In this step, we have to check whether there space bonds left to it is in formed.

If over there is a need of multiple shortcut formation, we need to create dual or triple bonds together per needs to accomplish the octet rule.

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

(A officially charge, likewise abbreviated together FC is the fee that is assigned come an atom the a molecule when we assume the chemical bond are always shared equally in between atoms within a molecule.)

Here is just how we can easily calculate the formal charge:


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

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

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

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

CS2 has actually 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 action 2, carbon is the the very least electronegative having actually the highest possible bonding sites. C is the main atom here.

3. The skeleton diagram of CS2 is attracted below.


4. We can check and also find the end that both the sulfur atoms have fulfilled your octet ascendancy here. But, carbon is the only one left v only four electrons bordering it.

We can easily mend this problem by share the electrons around sulfur and also bringing them together carbon, thus 2 valence electrons from each sulfur atom towards carbon will settle the trouble here.

5. We room therefore transforming the lone bag into twin bonds together per necessity.

6. Now, we require to examine the formal charge adhering to the given mentioned formula.

This is just how we attract a complete Lewis framework of Carbon disulfide.

Hybridization that CS2

Carbon disulfide has actually sp hybridization.

Now, what is hybridization? do you understand that atoms usage hybrid orbitals and not atomic orbitals to kind chemical bond in a molecule?

This procedure of hybridization is one of the crucial concepts of bonding and can be explained in two various methods- one through the aid of theory and also the other one depending upon formulae.


Let us very first make girlfriend go v the theoretical standpoint come make points easier!

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

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

C soil state configuration: 1s2 2s2 2p2

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

Just in the over section, while stating the Lewis structure we learned that in CS2 two double bonds room formed and also eight the the 16 valence electron are supplied up for this purpose.

The electron of 2s and 2p orbitals the C type the double bonds and also thus they an outcome in sp hybridization.

Here is a formula that deserve 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. It signifies the the hybridization type is sp.

Also, we can calculate the steric number.

Steric Number= No of sigma bond + No the pi lone pairs( the the main atom, here Carbon).

The octet has actually been fulfilled through the help of share valence electrons amongst the 2 sulfur and the carbon atoms, as such here over there is no lone pair.

There space two sigma bonds formed, hence steric number=2, sp hybridization.

Molecular Geometry that CS2

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

To identify the molecular geometry that a molecule, we need to get familiar with a principle called VSEPR theory.Now, what is the VSEPR theory?

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

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

Below is the chart the you deserve to refer to find the geometry the different varieties of molecules.


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

Thus, in the case of CS2, Sulfur is the external inspection atom.


Polarity of CS2

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

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

A polar molecule will an outcome due to unequal share of electron whereas non-polar ones space neutral.

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

From there, we can decipher the it is a direct molecule, for this reason the valence electrons around sulfur and also carbon room spread equally with no sulfur having actually a greater influence on carbon than the other one.

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

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

Also, you must examine out the post written top top the covalent nature that CS2.


Understanding of any type of molecule calls for a deep expertise intake of the inner chemistry and bonding structure.
