Question

why two carbon atom cannot form cova
lent bond to give c2​

Answer 1

Answer:

The reason a carbon atom cannot bond with four electrons with another carbon is due to the carbon electron orbitals. Since it has a s and 3 p orbitals, it must create one sigma and at most 2 pi bonds with another carbon. ... As you can see, there are two orbitals remaining and there's no physical way to make them bond.
