Question

Transition metal belonging to the 3d series having the lowest enthalpy of atomization in its most stable oxidation state forms oxide \( \text{MO} \). Nature of the oxide is:

• A. Highly acidic
• B. Amphoteric
• C. Highly basic
• D. Neutral

Hint:

Amphoteric oxides are those that can react with both acids and bases. Many transition metals form such oxides.

Answer 1

The Correct Option is B

Transition metals in the 3d series exhibit a wide range of oxidation states and form various types of oxides. The metal with the lowest enthalpy of atomization in its most stable oxidation state is generally the one that forms amphoteric oxides. Amphoteric oxides can react both with acids and bases. In this case, the transition metal with the lowest enthalpy of atomization forms an amphoteric oxide, which can react with both acidic and basic substances. Thus, the correct answer is (2) Amphoteric.
