Question

Which of the following transitions involves maximum amount of energy change?

• A. $M^{-}$(g) $\to$ $M\left(g\right)$
• B. $M\left(g\right)$ $\to$ $M^{+}$(g)
• C. $M^{+}$(g) $\to$ $M^{2+}$(g)
• D. $M^{2+}$​(g) $\to$ $M^{3+}$​(g)

Answer 1

The correct option is D

$M^{2+}$​(g) $\to$ $M^{3+}$​(g)

More energy is required to remove an electron from a cation with a higher positive charge.
