Question
State the reason why carbon can neither form C4+ cations nor C4− anions but forms covalent compounds.
Advertisements
Solution
To achieve a stable electron configuration, carbon typically either loses 4 electrons to create a C4+ cation or gains 4 electrons to produce a C4− anion. Both options are significantly energetically unfavorable. Carbon attains a stable electron configuration by sharing electrons via covalent bonding instead of acquiring or losing electrons.
