State the reason why carbon can neither form \[\ce{C^4+}\] cations nor \[\ce{C^4−}\] anions but forms covalent compound.
Give reason why carbon can neither form \[\ce{C^4+}\] cations nor \[\ce{C^4−}\] anions but form covalent compounds.
Solution
To achieve a stable electron configuration, carbon typically either loses 4 electrons to create a \[\ce{C^4+}\] cation or gains 4 electrons to produce a \[\ce{C^4−}\] 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.
