$Al_2O_3 \rightarrow Al$

Vedclass · Answer

(A) The reduction of $Al_2O_3 \rightarrow Al$ cannot be carried out using coke (carbon) because aluminum has a very high affinity for oxygen and is more stable than $CO_2$. It is instead carried out by the electrolytic reduction of its fused salts (Hall-Heroult process). $ZnO$,$Fe_2O_3$,and $Cu_2O$ can be reduced to their respective metals using carbon (coke) as a reducing agent.
