Question
Explain, giving reason, why carbon neither forms $C ^{4+}$ cations nor $C ^{4-}$ anions, but forms covalent compounds which are bad conductors of electricity and have low melting point and low boiling point.
✓
Answer
Carbon cannot lose $4 e ^{-}$to form $C ^{+4}$ cations, as very high energy is required to remove $4 e ^{-}$ Carbon cannot gain $4 e ^{-}$to form $C ^{-4}$ anions as nucleus with 6 protons cannot hold 10 electrons. Carbon can share $4 e ^{-}$to form covalent compounds.
Carbon compounds do not conduct electricity being non-polar and do not form ions/charged particles.
Due to weak intermolecular forces of attraction, carbon compounds have low melting points and boiling points.
