Question

Carbon is unable to form C4+ ion because ___________?

• A. It has tetra valency
• B. It gains electrons easily
• C. It shows catenation property
• D. Its formation requires a large amount of energy

Answer 1

Answer:

D. Its formation requires a large amount of energy

• Carbon has 4 valence electrons.

• To form C⁴⁺ ion, it would need to lose all 4 electrons which requires a large amount of energy.

• Therefore, it's difficult for carbon to form a C⁴⁺ ion.
