Carbon is unable to form C4+ ion because __________.

Correct option is B

The correct answer is (b) Its formation requires a large amount of energy.
Explanation:
· Carbon has 4 electrons in its valence shell, and to form a C⁴⁺ ion, it would need to lose all 4 electrons.
· This process requires a tremendous amount of energy because:
· The nuclear charge of carbon strongly holds onto its valence electrons.
· As electrons are removed, the effective nuclear charge on the remaining electrons increases, making it even harder to remove them.
· Consequently, forming a C⁴⁺ ion is not energetically favorable for carbon.
Information Booster:
· Instead of forming a C⁴⁺ ion, carbon prefers to share electrons to achieve stability, leading to covalent bonding.
· Carbon forms compounds through:
· Catenation: The ability to form long chains or rings by bonding with other carbon atoms.
· Tetravalency: Carbon forms 4 covalent bonds to achieve a stable configuration.
Key Facts:
· Carbon does not form C⁴⁻ ion either because:
· Adding 4 electrons would lead to strong electron repulsion.
· The ion would become highly unstable.
