Carbon dioxide is a colorless gas through chemical formula CO2 current in our setting with no odor at low concentration. We, humans, are also the source of this gas as we release carbon dioxide through our body in different forms. Many of friend may have doubts concerning whether the CO2 gas molecule is polar or not. We will comment on this and also will cover its properties and also uses.

You are watching: Why is a molecule of co2 nonpolar

So, Is CO2 polar or nonpolar? CO2 (carbon dioxide) is a nonpolar molecule due to the fact that of its straight symmetric shape. Back the carbon and oxygen different in your electronegativity as result of which C=O bond is polar, the polarity the both opposite C=O bonds get canceled by each other as result of symmetrical form and result in a nonpolar molecule through zero dipole moment.

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

Its naturally occurring sources are choose humans, geysers, volcanoes, and also many chemical reactions consisting of the dissolution of carbonate in water and acid.

It is soluble in water therefore also occurs in various water bodies choose groundwater. Rivers, lakes, etc.

Apart native humans, the is released by miscellaneous aerobic organisms on planet were castle metabolize the carbohydrates to release carbon dioxide gas.

If we talk around the chemical composition of the CO2 molecule, it is composed of one carbo atoms and also two oxygen atoms.

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

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

Carbon is the main atom surrounded by the two oxygen atoms on both sides. The shape of the molecule is straight as both oxygen atoms room opposite to each other.

The electronegativity that carbon is 2.55 and that that oxygen is 3.44. The difference between the electronegativity of both atom is sufficient to have polarity across C=O bond in the CO2 molecule.

But because of the the opposite of the molecule ie; linear structure, both C=O bonds lie opposite to each other, and also polarity the both gets canceled by each other.

The CO2 molecule is nonpolar and its dipole also turns the end to be 0 D.

Why is CO2 a Nonpolar Molecule?

The molecule of CO2 is polar since of the following reason.

The symmetrical geometry (linear) that the CO2 molecule cancels out the polarity of the C=O polar bonds because of which net dipole that the molecule becomes zero.

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

As a result, two oxygen atoms and carbon atom share 2 electrons the each other forming dual bonds across carbon and also 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 bonded electron pair slightly more towards that is side and also gains partial an adverse charge and also carbon gains partial positive charge.

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

Polar versus Nonpolar Molecules

The polarity of a molecule is made decision by the kind of bonding the involves across its atoms. The covalent bonds can be polar or nonpolar depending upon the miscellaneous factors.

Let us inspect the differences between the characteristics of polar and also nonpolar molecules

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

The dipole moment of this molecules is always zero.

There is no electronegativity difference in between the atoms throughout these molecules. It means bonded electrons are equally common by the atoms.

Some that the instances of this molecules are Hexane, CCl4. Girlfriend can check out the factor for the non-polarity the CCl4.

Polar Molecules: these molecules have actually unequal fee distribution across its atoms. There exists a difference between the electronegativity of the atoms.

More electronegative atom pulls the bonded electron pair towards it and also gets a relative negative charge. Whereas various other atom it s okay a relative positive charge.

The dipole moment of these molecules is no zero. Couple of examples of this molecules space SO2, H2O, etc. You can inspect out the reason for the polarity that SO2.

Important clues to determine the polarity that a molecule

Electronegativity: If there is a difference between the electronegativity that atoms forming a covalent bond, it ensures the polarity the the bond formed.

Higher electronegative atom traction the bonded electron in the direction of its next with greater influence and gains partial an unfavorable charge and becomes a an unfavorable pole that molecule whereas another atom i do not care a confident pole.

The polarity of a molecule is directly proportional come the difference in between the electronegativity of atoms.

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

It is additionally defined together the product the the fee on atoms and also the distance in between the centers of positive and an unfavorable charge.

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

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

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

Below is the picture of the shape of the molecule that CO2.


Properties of CO2

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

Uses that CO2

CO2 gas is widely provided for the purpose of refrigeration or cooling in our everyday life.This gas is likewise used in fire extinguishers together it stops the fire immediately.This gas is additionally used in industries for the production of casting molds to improve their hardness.CO2 gas is additionally present in soft drinks that we often consume.


CO2 molecule consists of one carbon atom and two oxygen atoms. Carbon and Oxygen form twin bonds (C=O) and also also type a linear structure.

Oxygen is much more electronegative 보다 carbon resulting in the C=O bond to it is in polar and also results in non zero dipole moment.

For more information concerning the geometry and lewis structure of CO2 molecule, girlfriend must likewise read the end the write-up written top top CO2 Lewis structure, molecular geometry, and also Hybridization.

But the dipole the both the contrary C=O bonds gets canceled through each other as result of the symmetrical molecular framework of CO2 making that a nonpolar molecule.
