✓ Answer: D Its formation requires a large amount of energy
Carbon cannot form a C4+ ion because removing four electrons requires a tremendous amount of energy. Due to carbon's small size and high ionization energy, it tends to share electrons rather than lose or gain them. This makes forming a C4+ ion highly unfavorable and impractical under normal conditions.
