Carbon Dioxide is among the finest compounds to begin with finding out the principles of Lewis structure and Molecular Geometry. This molecule deserve to be a an excellent start because that beginners who want to learn the fundamentals of such concepts and also want come know exactly how to draw Lewis dot structures for other molecules together well.

You are watching: What is the molecular geometry of co2

CO2 or Carbon Dioxide is comprised of two varieties of atoms: Carbon and also Oxygen. Although this gaseous molecule is recognized for its donation to the greenhouse effect and global warming, one can not deny the there are fairly a many uses because that this gas in several industries. 

To know the physics properties, reactivity, and also other chemical properties of a provided compound, the is vital to understand its molecular geometry. And also to help you know it, ns have discussed the CO2 Lewis structure and also its hybridization below.

CO2 Lewis Structure

One requirements to know the Lewis structure in stimulate to know the molecule geometry of any given molecule. This structure helps in learning the plan of electrons in the molecules and the form of the molecule. To understand the lewis structure of CO2, one should first understand what precisely the Lewis structure is.

Lewis dot framework is a pictorial representation of the plan of the valence shell electrons in the molecule. This valence electrons are represented by illustration dots roughly the individual atoms, thus the Lewis period structure. Drawing lines represent the bonds created in the molecule. 

Such structure helps in expertise the arrangement of atoms together with the electron participating in the bond formation. Currently that girlfriend know just how the Lewis structure is drawn and also its offers let us conveniently look at the CO2 Lewis structure.

In CO2, the Carbon atom is in the main position as it is the least electronegative atom in the molecule. Two Oxygen atom are located on the terminals where both these atoms share electron and form bonds through the main Carbon atom.

To recognize the shortcut formation and the arrangement, let’s go v the valence electrons of all the atoms in the molecule.

Valence electron in Carbon: 4Valence electrons in Oxygen: 6*2 = 12 ( as there space two Oxygen atoms in the molecule, we will certainly multiply the by 2)

Total variety of valence electrons in the molecule = 16


So, for now, place Carbon in the center position and draw four dots roughly it. In addition to the place, 2 Oxygen atom on both sides of the atom and draw six dots around each atom to stand for their valence electrons. 

You could know that a molecule demands to finish its octet to become stable and also inactive by achieve an electronic configuration comparable to the inert gases. This is excellent by one of two people donating one electron or by agree an electron. Here as the Oxygen atom are more electronegative than the Carbon atom, the Carbon atom will certainly donate its electron to both this Oxygen atoms.


Now, as 2 oxygen atoms need two electrons every to complete their octets, it will certainly share two electrons indigenous the Carbon atom and form dual bonds. Therefore each Oxygen atom will type a twin bond with the main atom. 

So now attract two parallel lines in between Oxygen atoms and Carbon atom to show double bonds in between the atoms. Because that Lewis structure of CO2, you will now have two Oxygen atom forming dual bonds v a Carbon atom. 


As every the valence electron of every the atoms space used, there room no lone bag of electron or non-bonding pairs of electron in the molecule. 

To further understand the molecule geometry the CO2, allow us quickly go through its hybridization and bond angle as it will certainly make it basic for united state to understand the geometry.

CO2 Hybridization

The electronic configuration of the Carbon atom in its soil state is 1s22s22p2, and also that of an Oxygen atom is 1s22s2p4. As soon as the electrons are in an excited state, they run to other orbitals. 


In that excited state, the atom’s electronic configuration i do not care 1s2 2s1 2p3, so currently every p-orbital of the atoms has actually one electron each. Below the 2s orbitals and also one the the p-orbitals will certainly hybridize to form 2 sp orbitals. In contrast, the Oxygen atom hybridizes to type three sp2 hybrid orbitals.

These two hybridized orbitals overlap with the two p-orbitals that the Oxygen atom that outcomes in the formation of sigma bonds. Continuing to be electrons in the p-orbitals in the Oxygen atom form pi bonds. 

As sp orbitals space hybridized to form the bonds, CO2 has an sp hybridization. 

CO2 molecule Geometry

The molecule Geometry of any compound is based upon the setup of atoms, electron pairs, and bonds. Right here in CO2, both Oxygen atoms form sigma bonds with the central carbon atom and complete your octet. As a result, there room no lone bag of electrons, yet bonding pairs of electrons additionally repel each other. Because of these repulsive forces between the valence covering electron pairs, the CO2 molecule repurchase a linear shape to keep the repulsion in ~ the least.


Hence CO2 has actually a linear molecular geometry v the bond angles of 180 degrees and symmetric circulation of electrons. 


To summarize this blog, we have the right to say the Carbon Dioxide has a direct molecular geometry. It has actually an sp hybridization and has bond angles of 180 degrees. There space no lone pairs of electrons in the molecule, and also there is a symmetric distribution of the electron in that is structure. As result of the repulsive forces between the bag of electrons, CO2 takes up linear geometry.
