Question

Which of the following transitions involves maximum amount of energy?

• A. \( M^- (g) \rightarrow M(g) \)
• B. \( M^- (g) \rightarrow M^+ (g) \)
• C. \( M^+ (g) \rightarrow M^{2+} (g) \)
• D. \( M^{2+} (g) \rightarrow M^{3+} (g) \)

Hint:

Transitions involving higher oxidation states, like \( M^{2+} \rightarrow M^{3+} \), require more energy than transitions involving smaller charge differences.

Answer 1
