Carbon dioxide is a colorless gas v chemical formula CO2 existing in our environment with no odor at short concentration. We, humans, are likewise the resource of this gas as we release carbon dioxide with our body in various forms. Many of friend may have doubts regarding whether the CO2 gas molecule is polar or not. We will talk about this and also will cover its properties and uses.

You are watching: Carbon dioxide is a nonpolar molecule

So, Is CO2 polar or nonpolar? CO2 (carbon dioxide) is a nonpolar molecule due to the fact that of its direct symmetric shape. Back the carbon and also oxygen different in their electronegativity as result of which C=O link is polar, the polarity the both the contrary C=O bonds acquire canceled by every other because of symmetrical shape and an outcome in a nonpolar molecule with zero dipole moment.

Carbon dioxide gas is colorless and also odorless in nature and its thickness is 60% greater than the of dry air about us. That is a naturally developing gas in the earth atmosphere.

Its naturally arising sources are choose humans, geysers, volcanoes, and also many chemistry reactions including the dissolution of carbonate in water and acid.

It is soluble in water therefore also occurs in miscellaneous water bodies favor groundwater. Rivers, lakes, etc.

Apart from humans, it is released by various aerobic biology on planet were lock metabolize the carbohydrates to release carbon dioxide gas.

If we talk about the chemical composition that the CO2 molecule, it consists of one carbo atoms and also two oxygen atoms.

The molecular mass that CO2 is 44.009 g·mol−1. It is calculated together below

Mol mass of CO2 = 1 * 12(Mol massive of C) + 2 * 16 (Mol mass of O) = 44.009 g·mol−1

Carbon is the central atom surrounded by the 2 oxygen atom on both sides. The form of the molecule is direct as both oxygen atoms are opposite to every other.

The electronegativity that carbon is 2.55 and also that of oxygen is 3.44. The difference in between the electronegativity of both atoms is sufficient to have actually polarity throughout C=O binding in the CO2 molecule.

But because of the symmetry of the molecule ie; direct structure, both C=O bond lie opposite to each other, and polarity of both gets canceled by every other.

The CO2 molecule is nonpolar and also its dipole additionally turns out to be 0 D.

Why is CO2 a Nonpolar Molecule?

The molecule of CO2 is polar because of the adhering to reason.

The symmetrical geometry (linear) the the CO2 molecule cancels out the polarity of the C=O polar bonds due to which net dipole the the molecule i do not care zero.

The valence electrons of oxygen are 6 and that that carbon is 4. Oxygen needs 2 electrons to complete its octet and carbon requirements 4 for the same.

As a result, two oxygen atoms and carbon atom share two electrons the each various other forming double bonds throughout carbon and oxygen atoms and fills their octet to get stabilized.

The oxygen atoms lie at both sides of the carbon atom. And oxygen being an ext electronegative pulls the external inspection electron pair slightly an ext towards the side and also gains partial negative charge and also carbon profit partial optimistic charge.

The dipole throughout the C=O bond is no zero and originates towards oxygen, however the equal and also opposite dipoles cancel out each other leading to a nonpolar molecule.

Polar matches Nonpolar Molecules

The polarity that a molecule is chose by the kind of bonding the involves throughout its atoms. The covalent bonds can be polar or nonpolar depending upon the assorted factors.

Let us examine the differences in between the attributes of polar and also nonpolar molecules

Non-Polar Molecules: this molecules are electrically neutral and also in this molecules, bonded shared electrons space at equal distance from both atoms developing a covalent bond.

The dipole moment of these molecules is always zero.

There is no electronegativity difference between the atoms throughout these molecules. It method bonded electrons space equally common by the atoms.

Some that the instances of these molecules are Hexane, CCl4. Friend can check out the reason for the non-polarity the CCl4.

Polar Molecules: this molecules have unequal charge distribution across its atoms. There exists a difference in between the electronegativity the the atoms.

More electronegative atom traction the bonded electron pair towards it and also gets a relative an adverse charge. Whereas various other atom gets a relative hopeful charge.

The dipole moment of these molecules is non zero. Couple of examples of this molecules space SO2, H2O, etc. Girlfriend can examine out the factor for the polarity that SO2.

Important point out to recognize the polarity of a molecule

Electronegativity: If there is a difference between the electronegativity of atoms developing a covalent bond, it guarantee the polarity of the shortcut formed.

Higher electronegative atom pulls the bonded electron towards its side with better influence and gains partial negative charge and also becomes a negative pole the molecule whereas another atom becomes a hopeful pole.

The polarity that a molecule is directly proportional to the difference between the electronegativity the atoms.

Dipole Moment: The dipole the the polar molecules is always non zero. It is the measure up of the polaroid of a molecule.

It is also defined together the product of the charge on atoms and also the distance in between the centers of confident and an adverse charge.

Its Si unit is Debye and also is denoted through D.

Geometrical Shape: If girlfriend look at the shapes of the nonpolar and polar molecules, friend will discover that nonpolar molecules normally have symmetric form whereas polar molecules have asymmetric (distorted) shapes.

Due come the symmetric shape of nonpolar molecules, the charge circulation remains uniform on its atoms.

Below is the image of the shape of the molecule the CO2.


Properties that CO2

It exists as a colorless gas in appearance.The density of this gas is 1.98 kg/m3 the is 1.67 times to the of dried air.At a temperature of 20 °C, the vapor push of this gas is 5.73 MPa.The melting allude of CO2 is −56.6 °C or −69.8 °F.The geometrical form of the molecule that CO2 is linear.The dipole minute of CO2 is 0 D.It is soluble in water as such present in the water bodies choose groundwater, rivers, lakes, etc.

Uses of CO2

CO2 gas is widely offered for the objective of refrigeration or cooling in our everyday life.This gas is also used in fire extinguishers as it stops the fire immediately.This gas is also used in industries for the manufacturing of spreading molds to enhance their hardness.CO2 gas is additionally present in soft drink that we often consume.


CO2 molecule is composed of one carbon atom and two oxygen atoms. Carbon and also Oxygen form dual bonds (C=O) and also also form a direct structure.

Oxygen is much more electronegative 보다 carbon bring about the C=O shortcut to it is in polar and also results in no zero dipole moment.

For an ext information concerning the geometry and lewis framework of CO2 molecule, friend must additionally read out the post written ~ above CO2 Lewis structure, molecular geometry, and also Hybridization.

But the dipole the both opposite C=O bonds gets canceled v each other due to the symmetry molecular structure of CO2 making that a nonpolar molecule.
