Why does carbon form compounds mainly by covalent bonding?
- There are four electrons in the outermost shell of carbon.
- It requires large amount of energy to form C4+ or C4-.
- It shares its valence electrons to complete its octet.
- All the above.
Correct Answer: (d) All the above.
Explanation: Carbon form compounds mainly by covalent bonding because it has four electrons in its outermost shell and requires a large amount of energy to form C4+ or C4-. Carbon shares its valence electrons to complete its octet.
