From the time we were in school, we knew that us inhale oxygen and also exhale CO2. Yet is the all we have to know?

Probably no! together we indulge an ext in chemistry, we deserve to see, there room many much more things regarded CO2. To learn all those points smoothly we should know about this gas in an ext detail.

You are watching: The hybridization of the carbon atom in carbon dioxide is ________.

So without more adieu, let’s quickly jump into the “ Carbon dioxide world”!!

This gas has a different use in different fields. Native being used as a refrigerant to carbonated beverages, CO2 is everywhere. We need to not forget how vital it is for the plants!!

It is supplied in various industries as well.

The molar mass of CO2 is 44.009 g/mol and also density is 1562 Kg/m3. Now let us learn the basic concepts about CO2 molecules.

CO2 Lewis Structure

The lewis framework of CO2 can be through some basic steps, but prior to that, it is necessary to know lewis framework properly.

So lewis structure normally gives us an idea about the nature of bonding and also octet fulfillment the the atoms. According to the octet rule, one atom attains stability by fulfilling that is octet.

For example, in CO2, carbon needs 6 electron to satisfy the octet, whereas oxygen needs only 2 electrons.

Now, allow us quickly go through the measures for creating a lewis framework of any type of compound.

Step 1 – very first and foremost we should calculate the total valence electrons present in the molecule. Treatment should it is in taken regarding +, – signs. A ‘+’ sign way losing electrons and also ‘-‘ means gaining.

Step 2 – following we need to number out the central atom that the molecule. Mainly the atom with the greatest bonding sites is the central atom.

Step 3 – next step will certainly be, developing a skeleton comprise only solitary bonds.

Step 4 – climate we need to complete the octet the the atoms with the electrons left. The advisable, to start with, the electronegative atoms and then the electropositive ones.

Step 5 – after ~ that, we should ensure if over there is a requirement of multiple bonds because that fulfilling the octet preeminence of every atoms.

Step 6 – at the finish ensure all the atoms are in their lowest feasible formal charge. The calculation because that formal charge deserve to be done utilizing the formula provided below:-


Now let’s move on to the lewis structure of CO2,


Number that valence electrons of carbon = 4

Number of valence electrons of oxygen = 6

Number of valence electrons because that 2 oxygen atoms = 6*2 = 12

Total valence electron = 16

Now, while deciding the main atom, notification that carbon has actually the highest possible bonding sites. Hence carbon is the main atom that this molecule.

Following up the step and also after illustration the bones diagram, we see that 4 electrons are supplied so far. Still, 12 electrons are remaining.

But, looking at the octet of atoms, observe the carbon’s octet is no fulfilled. Hence according come the rule, an altering the lone bag into twin bonds is necessary.

Now, the continuing to be electrons will certainly be 8. These 8 electrons are distributed among the surrounding atoms.

In the end, check that carbon and also oxygen both are having 8 electrons. Also, both are having actually the lowest feasible formal charge.

Thus the lewis structure of CO2 is formed using 4-5 straightforward steps!

CO2 Hybridization

The hybridization the CO2 is Sp. The carbon atom is Sp hybridized and also oxygen atoms are Sp2, do the overall molecule Sp hybridized.


Hybridization have the right to be understood by 2 methods, one by knowledge the mix of the orbitals and 2nd by using a simple formula.

Let’s know the theory first and climate we can use the formula easily!

The ground state construction of C = 1s2 2s2 2p2

And ground state construction of O = 1s2 2s2 2p4

Now as soon as the atom reach your excited state, 1 electron native the 2s orbit of carbon jumps to vacant orbital 2p. Thus brand-new configuration becomes – 1s2 2s1 2p3

This leads to the formation of 2 Sp orbital including one electron the 2s and also 1 electron of 2p orbital of the carbon atom. The ns orbitals of oxygen combine with the hybrid orbitals formed and a sigma bond is formed.

This explains the theory of hybridization in CO2. Currently let’s come to the amazing part! The formula!!

The formula to uncover the hybridization of any kind of compound is,

H = ½ < V+M-C+A>


H represents the hybridization, V to represent the number of valence electrons, M to represent the number of the monovalent atom, C represents the fee of the cation, and also A to represent the fee of the anion

Now if H is 2, climate it’s Sp hybridization

Likewise, if H= 3, it indicates Sp2 hybridization.

In the same way, once H is 4, the molecule will display Sp3 hybridization

When H is 5, it will certainly Sp4 hybridization

And, once H is 6, the molecule will show Sp3d2 hybridization.

For CO2,

No. Of valence electrons of the center atom (V) = 4

Here, M = 0, since oxygen is a divalent atom.

As CO2 is a neutral molecule, C and A will be 0 here.

Finally, H = ½ <4>

= 2 = Sp hybridization

These two ways are typically used to recognize the hybridization the CO2.

CO2 molecule Geometry

CO2 has a straight shape. The bond edge of CO2 is 180°.

The molecular geometry of any kind of compound can be determined by the VSEPR theory. The VSEPR chart is attached below, i m sorry will offer us one idea around this.


So from the above chart, it’s clear the CO2 is one AX2 type molecule, where X= bonded atom

Thus the molecule geometry of the CO2 molecule will be linear.

The electron geometry that CO2 is direct as well. Prior to you bombard me v questions around electron geometry, permit me clean it out!!

So molecular geometry is those which incorporate only the atom while determining the shape of the molecule. Vice versa, electron geometry contains all electron pairs.

Likewise, electron geometry will encompass the lone pairs as well, which create the difference in between these two varieties of geometry.

CO2 no have any lone pair, therefore both geometries room the exact same in this case.

Let’s relocate on to the molecular orbital diagram the this compound.


CO2 Molecular orbit (MO) Diagram

The molecular orbital diagram the CO2 is as below.


A molecular orbit diagram of any type of compound gives us one idea about the bonding the the orbitals. It also helps united state to find the shortcut order, bond length, bond strength of the molecule.

In the diagram, the left-hand side consists of the atom orbitals the carbon. Likewise, the left side has AO’s of oxygen. And also in the middle is the MO.

We deserve to see the the 2s orbital of oxygen is not connected in mixing and also remains a nonbonding orbital. The reason for this is the high energy difference in between the orbitals that carbon and also the 2s orbit of oxygen.

All the 16 electrons are filled specifically as per rules. The antibonding orbitals room vacant in the case of CO2 together observed native the MO diagram.

Apart from these concepts, permit us also study the approaches of development of CO2 gas.

CO2 Polarity

The CO2 molecule is direct in shape and therefore both oxygen atoms have actually equal influence on the fee making CO2 a nonpolar molecule.

The molecule does not exhibit any kind of polarization since of no dipole minute generated across the molecule.

For much more detailed information, girlfriend can also refer to the short article on CO2 polarity.

CO2 Preparation

Process 1- CO2 is created when calcium lead carbonate is reacted through hydrochloric acid.2HCl + CaCO3 ——–> CO2 + CaCl2 + H2O

This is the easiest method used in the activities for CO2 formation.

Process 2 – Another means is the combination of methane and also oxygen.CH4 + 2O2 ——-> CO2 + 2H2O

This technique indicates the all the carbon-based fuel can develop CO2 by the procedure of combustion.

Process 3 – 3rd process used to prepare CO2 is the thermal decomposition the CaCO3.CaCO3 ——-> CaO + CO2

Calcium carbonate is cook at around 850℃ in this process. The CaO created in this procedure is well-known as fast lime and is also used commonly in industries.

Process 4 – Carbonic acid is supplied to create CO2. The decomposition of this mountain leads come the formation of CO2 and also water.H2CO3 ——–> CO2 + H2O

This process is widely supplied in industries since the development of foam or bubbles, as result of the release of CO2, neutralizes the waste mountain streams.

Process 5 – Fermentation of different alcoholic beverages, prefer beer, whisky, leads to CO2 development as a by-product.C6H12O6 ———> 2CO2 + 2C2H5OH

Process 6 – The Respiration procedure of glucose release CO2 and also water together products.C6H12O6 + 6O2 ——-> 6CO2 + 6H2O

Next, we should know about the lewis structure, geometry, and also hybridization the CO2.


As I said earlier, to know the use of carbon dioxide smoothly, we need to learn the elevator of this gas beforehand. This background requires lewis structure, hybridization, molecule geometry, and molecular orbit diagram.

All the available details about these topics are jotted down in this article.

After this, girlfriend can conveniently go through any other topic regarded CO2. I hope at the end of this article you get the answers to your long searched questions!! have a happy learning.
