Higher the E text red ° value, higher stability.

Q. Amongst the following ions, which is considered as most stable in $M^{2 +}$ state?

$T i^{2 +} / T i (- 1.63 V)$

$V^{2 +} / V (- 1.11 V)$

$C r^{2 +} / C r (- 0.90 V)$

$M n^{2 +} / M n (1.18 V)$

Higher the $E_{red}^{\circ}$ value, higher stability.
