Carbon de defiders is a chemistry compound through chemical formula CS2. That is a colorless fluid in appearance and is volatile in nature. It has actually a sweet odor like that of ether. Plenty of students may likewise have doubts regarding whether CS2 is polar or not. In this article, I will certainly answer this and will covering its properties and also uses.

You are watching: Is cs2 polar or nonpolar molecule

So, is CS2 polar or nonpolar? CS2 (Carbon disulfide) is nonpolar due to the fact that of the symmetric (linear) shape. Although carbon and also sulfur different in their electronegativity and C-S shortcut is polar, the polarity the both the contrary C-S bonds gets canceled by every other resulting in a nonpolar molecule.

Carbon disulfide exists in the liquid state in ~ standard conditions of temperature and also pressure. The smells sweet favor ether.

This link is thought about as the building block in the people of essential chemistry. It is widely offered in the sectors as a non-polar solvent.

It is a extremely flammable liquid. Its combustion produces SO2 and also CO2 gas fumes.

CS2 (Carbon disulfide) + 3O2 (Oxygen) —-combustion—-> CO2 (carbon dioxide) + 2SO2(sulfur dioxide)

The molecule mass of this link is 76.13 g·mol−1. It is calculated as

Mol mass of CS2 = 1 * 12(Mol mass of C) + 2 * 32(Mol mass of S) = 76.13 g·mol−1.

The chemical composition the this problem is such the it is composed of 1 carbon and 2 sulfur atoms.

The carbon atom is the central atom surrounded by 2 sulfur atom on both sides. The Sulfur atoms about both political parties (left and also right) create the form of a molecule is linear.

The electronegativity that carbon is 2.55 and that the Sulfur is 2.58 as result of which the C-S bonds end up being slightly polar.

The slightly polar bonds in opposite directions cancel the end the polarity v each other and nullify the as whole polarity the the molecule.

The dipole of the whole molecule transforms out to it is in 0 D.

Difference in between Polar and also Nonpolar Molecules

The molecules that are hosted by the covalent bonds can be polar. Let us know the covalent bonds.

Covalent bonds room the types of chemical bonds in which atoms share electron of each various other to get stabilized.

These bonds deserve to be single, double, and triple depending upon the basis of the variety of electrons participated in bond.

Non-Polar Molecules: The non-polar molecules are the molecule in i beg your pardon the charges are uniformly spread throughout the molecule such the no atom share unequal charge.

The dipole moment of together molecules has zero value. The covalent shortcut formed in between two atoms is non-polar if the atoms have equal electronegativity.

These molecule may also consist the polar bonds within them, but due come the symmetrical shape, the polarity of such bonds it s okay canceled through each other making the molecule a nonpolar.

Some of the instances of this molecules are BF3, Cl2, O3. Girlfriend can inspect out the factor for the non-polarity of C2H4.

Polar Molecules: The nonpolar molecules room the molecule that have actually unequal distribution of charge across its atoms.

The dipole minute of together molecules is always non zero. The bond formed by a diatomic molecule is claimed to be polar if they different in your electronegativity.

This is because greater electronegative atom pulls the external inspection electronegative fee slightly towards it and also gains a partial an unfavorable charge.

Few examples of nonpolar molecules space HCl, HBr, etc. Girlfriend can inspect out the reason for the polarity the SCN.

Why is CS2 a Nonpolar Molecule?

As disputed the molecule that carbon disulfide consists of 1 carbon and 2 sulfur atoms on that both sides and also forms a symmetric linear-shaped molecule.

The symmetrically shaped molecules are usually nonpolar. Similarly, the CS2 molecule is non-polar due to the fact that of complying with reason,

There exists a tiny difference in between the electronegativity of carbon and also sulfur atom that provides the C-S a contempt polar bond.

Both C-S bonds have actually dipoles in opposite directions as a result it cancels every other and net dipole turns out to it is in zero.

Therefore, it is usually observed that symmetrically shaped molecules tend to be nonpolar in nature.

Instead of having actually polar bonds, the molecule is nonpolar.

Lewis Structure and also Geometrical framework of CS2

Lewis structure of a molecule is additionally known as electron dot structure because it represents the variety of valence electron of the molecule that take authorized in the link formation.

In lewis structure, the lines signify the bond developed in the molecule and also dot to represent the non bonded electrons.

Lewis structure is dependent on the octet rule. Octet rule principles mean that the atom should have eight electrons in that is outermost shell to accomplish its stability.

In CS2 molecule, Carbon has 4 valence electrons and also the Sulfur atom has 6 valence electrons. This renders a total of 16 valence electrons of the CS2 molecule.

Carbon is the least electronegative atom in the molecule thus it becomes the central atom.

Both Sulfur atoms kind a dual bond with the carbon shortcut to complete their octet leave behind 2 lone pairs on both Sulfur atom.

And the geometrical form of the molecule becomes linear having actually sulfur atom at both ends. The bond length of the C-S bond is about 155.26 pm.

Below is the photo of the geometrical form of the CS2 molecule.


Important point out to determine the polarity that a molecule

While checking if a molecule is polar or not. You need to note down the adhering to properties that assist to check its polar nature.

Let us check what the listed below factors actually means.

Electronegativity: The electronegativity that the atom in a molecule have to be noted down. If you see the difference in between the electronegativity of its atoms. It means the bond created by them is polar.

Two atoms that kind a covalent polar shortcut will constantly differ in their electronegativity.

This is since a greater electronegative atom will attract the external inspection electron pair towards its side and also gain an unfavorable charge and also other tom it s okay a partial positive charge.

The polarity the a molecule is straight proportional come the difference between the electronegativity that its atoms.

Dipole Moment: This term is supplied to measure up the extent of the polarity of a molecule. The polarity that a molecule is straight proportional come its dipole moment.

Basically, that is the product that the dues on atoms and also distance between the centers that their hopeful and an unfavorable charge.

It is denoted through D with its SI unit Debye.

Geometrical Shape: The form of a molecule is a very important parameter that have the right to make the polar or non-polar.

It is normally seen the geometrically distorted molecules space polar because they have actually charge imbalance.

Whereas the symmetrically shaped molecules room non-polar in nature since the charge distribution in this molecules is uniform.

Properties that CS2

It exists as a liquid v a colorless appearance.In pure form, it smells sweet together ether. But commercially, it is added with impurities leading to a foul smell.Its melting allude is −111.61 °C or −168.90 °F and also its boiling suggest is 46.24 °C and 115.23 °F.This compound is one organosulfur compound.At a temperature that 20 °C. That solubility in water is 2.17 g/L.At a temperature the 25 °C, the vapor push of this compound is 48.1 kPa.It is volatile ie; evaporates at room temperature.

Uses that CS2

This substance is widely supplied for the production of perfumes and also other fragrance products.It is additionally used in the manufacturing of rayon, rubber in textile industries.This liquid is also present in the insecticides supplied in the chop fields.Carbon de defiders is considered as a structure block in organic chemistry.In smaller quantities, the is offered in miscellaneous solvent exploit processes.


Carbon disulfide is composed of 1 carbon atom and 2 sulfur atom on both political parties of carbon make a linear-shaped molecule.

Although over there is a tiny difference between the electronegativity the Carbon(2.55) and also Sulfur(2.58) that renders the C-S bond contempt polar, the molecule is nonpolar due to symmetric form of CS2 molecule.

The dipole the both C-S binding is equal and in the opposite directions that cancel by each other making CS2 molecule non-polar.
