medium
Which of the following reduction reaction CANNOT be carried out with coke?
A
$Al _{2} O _{3} \rightarrow Al$
B
$ZnO \rightarrow Zn$
C
$Fe _{2} O _{3} \rightarrow Fe$
D
$Cu _{2} O \rightarrow Cu$
(JEE MAIN-2021)
Solution
Reduction of $Al _{2} O _{3} \rightarrow Al$ is carried out by electrolytic reduction of its fused salts.
$ZnO , Fe _{2} O _{3} \& Cu _{2} O$ can be reduce by carbon.
