![]() ![]() Repeat the same process now to the other Oxygen electron. And the carbon has 6, which is a bit closer. Now, it’s time to share these nonbonding electrons between both atoms! It will look as shown below if we started from considering the Oxygen atom.Īs we can see, Oxygen has 8 electrons, which is perfect. But, the carbon has only 4 valence electrons it does not have octets. The oxygen on the right has 8, and the left has 8. Now, let’s check and see whether we have octets. Then, we can complete the octets on the outer shell. Now, let us place an electron pair between each of these oxygen atoms. So, place the Carbon in the middle and then keep the oxygen either side of that! So, the total valence electrons are 16.Ĭarbon is the least electronegative, which means it stays at the centre. Carbon is in group 4, whereas oxygen is in group 6. The formation of CO 2 consists of two particles: Oxygen and Carbon. The unhybridized p orbital is used to form a pi bond, and out of three sp hybrid orbitals, only one will be used to form a bond with Carbon. The remaining two p electrons will be used to form a pi (π) bond.Īlso, oxygen hybridizes its orbitals to form three sp2 hybrid orbitals. Out of two hybrid orbitals, one will be used to produce a bond with one oxygen atom, and the other will be used to produce a bond with another oxygen atom. The type of hybridization in CO 2 is sp hybridization, and each carbon atom forms two sp hybrid orbitals. So, one electron from 2s orbital jumps from the 2s level to 2p level, and the orbitals hybridize to form the hybrid orbitals. The 2pz now can overlap with the unhybridized 2pz on the carbon to form a resultant π bond.A similar process can happen on the other side of the carbon forming another π bond with the 2py orbitals from each atom and σ bond with Oxygen’s 2pz.Ĭarbon has 6 electrons, whereas Oxygen has 8 electrons.īefore hybridization, the Carbon atom has 2 unpaired electrons to form bonding, which is not enough to form bonds with an oxygen atom. The 2px now can overlap with one of the sp hybrids from the carbon to form a resultant σ bond. Two of the 2p orbitals, for example, the 2px and 2pz, only hold one electron. Oxygen has the 1s2 2s2 2p4 electron configuration of the ground state. The 2s orbitals and one of the 2p orbitals, for suppose, the 2py can hybridize and produce 2 sp hybrid orbitals. Each of the 2p orbital, 2px 2py, 2pz now holds one electron. We can consider one of the 2s electrons to be excited to fill the other empty 2p orbital to provide a 1s2 2s1 2p3 configuration. The properties of CO 2 like molecular name, the formula can be tabulated below.Ĭarbon’s electron configuration is 1s2 2s2 2p2 in the ground state. We can also determine this closely by observing each atom of CO 2. Bonds can be either one single + one triple bond or two double bonds. This hybridization type occurs as a result of carbon being bound to the other two atoms. However, out of these three sp hybrid orbitals, only one will be used to produce a bond with the carbon atom.Ĭarbon dioxide has an sp hybridization type. The p orbital in the oxygen atom remains unchanged and is primarily used to form a pi bond. In the carbon dioxide molecule, oxygen also hybridizes its orbitals to produce three sp2 hybrid orbitals. They are used to form a pi bond as for the two remaining p electrons. Now, these hybridized sp orbitals of carbon atoms overlap with two p orbitals of the oxygen atoms to produce 2 sigma bonds. So, then, one electron from 2s orbital moves from the 2s level to the 2p level that results in the formation of two hybrid orbitals. However, this is not enough to produce bonds with oxygen. The carbon atom has two double bonds, or two effective pairs exist in it. To determine the hybridization of carbon dioxide, let us take the carbon atom first. ![]()
