Can a carbon atom share its all four electrons with other atom of carbon to attain stable configuration?

Question

For example....
O2 is oxygen...
H2O is water..

I wanted to kno whether we can form a compound named "C2"

Answer 1

No. Because the covalent bond is not strong enough and the position of the electron bonds will not be stable. The geometry structure of the electrone is impossible.

In short, they can't bond together to form C2.

Answer 2

No, because there are no orbitals available which have a low enough energy and are of the correct orientation to allow for overlap to create the fourth bond.

Quadruple bonds are seen in some metal complexes where the fourth bond is a delta bond, arising from two d-orbitals which are parallel to each other where all four lobes of the orbitals overlap. The nearest d-orbitals available for carbon are the 3d set, so the energy lost by placing electrons that high would not be made up by the energy gained from forming the fourth bond.

Answer 3

No, because of the arrangement of electrons, molecular torsion effects prevent it from sharing all 4 e- with another C atom... it usually can covalently share an electron with 4 other C atoms giving rise to the crystalline structure we know as diamond, or can associate by means of 6C ring strucures and weak van der Walls forces to give rise to graphite, as is used in modern pencils. There are also 'hollow ball' conformations, but they don't form easily.

Answer 4

u cant form c2 instead u can form c4. c2 is highly unstable
