Answer:
There is one single covalent bond between two carbon atoms.
Explanation:
We know that sharing of electrons form covalent bonds.
If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.
We found that Hydrogen is having only electron in K shell.
And Carbon on the other hand is having electrons in K shell and
electrons in L shell.
So carbon have valence electrons,and it can share
bonds with any relevant atom to complete its octet.
And Hydrogen requires electron to complete its doublet.
Alkane general formula
For ethane
Carbon atom is shared by
Hydrogen.
The remaining one electron of carbon will be shared with another carbon atom.
An image of the sharing of electrons attached below,
Hence we have only covalent bond between the two.
