Why can oxides of highly reactive metals not be reduced by carbon?
(N/A) Highly reactive metals (such as $Na, Mg, Ca, Al$) have a much stronger affinity for oxygen than carbon does. Because their bond with oxygen is significantly more stable,carbon is unable to displace the metal from its oxide. Therefore,these metals are extracted from their ores by electrolytic reduction rather than carbon reduction.
