Can anyone tell me the covalent bonding of ethylene and CO2?

Question

A diagram would also be helpful or a website?

I meant the covalent bond of ethylene (C2H4) and CO2

I meant the covalent bond of ethylene (C2H4) and CO2

Answer 1

Ethylene [ethene]:- In ethylene carbon hybridisation is sp2.
first you see the electronic configuration of carbon. 1s2 2s2 2p2.
2s2 2p2 is the valence shell. Now one electron from 2s orbital excites in to 2p orbital. Now in the excited state carbon contains one unpaired electron in 2s orbital and three unpaired electrons in three 2p orbitals. one 2s orbital and two 2p orbitals participate in hybridistaion to form three sp2 orbitals means carbon still has one unhybridised 2p orbital with unpaired electron.
Each carbon utilises its two sp2 orbitals to form two covalent bonds with two hydrogen atoms each. These two cavalent bonds formed due to the overlap of carbon's sp2 with half filled 1s orbital of hydrogen. The remaining one sp2 orbital of each carbon atoms overlap with each other to form one covalent bond between two carbon atoms. so till now totally five covalent bonds are formed. these bonds are called sigma bonds which are strong and formed due to the direct head to head overlaping.
Now each carbon still contains one unhybridised half filled 2p orbital. These two 2p orbitals overlap with each other to form anothe covalent bond which is also called as pi bond. this is a weaker bond than sigma bond and is formed due to the lateral verlapping of p orbitals. there fore ethylene in total consists 5 sigma bond and 1 pi bond.

CO2:- In CO2 the hybridisation of carbon is SP. One 2s and one 2p orbital of carbon[ excited state] participate in hybridisartion to form two sp hybrid orbitals. means the carbon atom consists two half filled sp hybrid orbitals and two unhybridised half filled 2p orbitals. As you know oxygen consists two half filled 2p orbitals in the valence shell which participate in bond formation.
Now one sp orbital of carbon overlaps with half filled 2p orbital of one oxygen atom and second sp orbital of carbon overlaps with half filled 2p orbital of second oxygen atom to form two sigma bonds. Still each oxygen atom contains one half filled 2p orbital. the two half filled 2p orbitals of carbon atom overlaps with half filled 2p orbitals of each oxygen atom to form two pi bonds.

Answer 2

First of all, as Strange_Days very correctly commented, the bonds are polar but the molecule is not because the dipole moments of the two polar bonds cancel each other. CO2 is a nonpolar molecule. Some nonpolar gases can dissolve in water, though to a small degree, due to induced dipole-dipole interactions. That's how some hydrates like with noble gases or methane form. Also don't forget that O2 is also nonpolar but still dissolves at levels enough to sustain marine life. The solubility of a gas in water increases if it can react/dissociate in water. Vovozinha very nicely explained how dissolved CO2 froms H2CO3 which dissociates further to various ions. It also depends on factors such as temperature, pressure (and the ionic strength of a solution if we are not talking about pure water).

Answer 3

I would use = to mean double bond and - to mean single bonds I the part for answers is not diagram friendly so I hope this helps

O = C = O
It has a linear shape

the first link might be useful to you
and the second link is to pictures of ethene which is C2H4
which is ethene not ethylene

Answer 4

Covalent bonding occurs by a sharing of valence electrons, rather than an outright electron transfer. Similarities in physical properties (they are all gases) suggest that the diatomic elements H2, N2, O2, F2 & Cl2 also have covalent bonds.

Answer 5

the covalent bonding in ethylene is a double covalent bond.
its structure is :(there two hydrogen single bonds with each carbon atom)
H-C=C-H
I I
H H
structure of co2 is:
O=C=O
it is double covalent bond

Answer 6

H H
\ /
C=C and O=C=O
