What is the ionic bonding of C-Cl?

Answer 1

C represents Carbon, Cl represents Chlorine, therefore C-Cl represents Carbon Tetrachloride. The ionic structure is normally initiated automatically, however some times a little kick is needed (however Chlorine is highly reactive):

Carbon has 2 electrons on its innermost shell (2e) then it has 4e (which means it needs 4 to make a complete octet).

Carbon- 6 (6 electrons) + Chlorine 17 (17 electrons)

----------------------------------->

Carbon- 10 (charge 4-) + Chlorine 13 (charge 4+).

Chlorine now has 2e on its innermost shell, then 8e, then 3e.

the equation is incomplete because there are 3 electrons left on the outer shell for Chlorine. so if we double it:

2 Carbon- 6 + 2 Chlorine 17 -> 2 Carbon- 10 (4-) + 2 Chlorine 13 (4+)

this leaves 6 electrons spare for Chlorine so we double it again:

4 Carbon- 6 + 4 Chlorine 17 -> 4 Carbon- 10 (4-) + 4 Chlorine 13 (4+)

this leaves us with 12 spare electrons.

12 spare electrons can be shared equally with 3 Carbon to give them all a full outer shell thus: 7 Carbon + 4 Chlorine -> Carbon Tetrachloride (4X Chloride).

Answer 2

In the case of C-Cl, the bond between carbon and chlorine is mostly considered covalent rather than ionic. Ionic bonds typically form between atoms with a large difference in electronegativity, while covalent bonds occur when atoms share electrons more equally. In the C-Cl bond, the electronegativity difference is not large enough to form a true ionic bond.
