The metal oxide, which cannot be reduced to metal by carbon is:
Correct answer: D. Al2O3
- A. ZnO
- B. Fe2O3
- C. PbO
- D. Al2O3
Explanation
Option D is correct.Aluminum oxide (Al2O3) cannot be reduced to metal by carbon. Carbon is a good reducing agent, but it is not strong enough to reduce aluminum oxide. Aluminum oxide is a very stable oxide and requires a strong reducing agent, such as sodium or magnesium, to be reduced to metal.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
