S-I:

\mathrm{Fe}^{+3}

ion is less stable than

\mathrm{Fe}^{+2}.

S-II :

\mathrm{Fe}^{+3}

ion has less number of unpaired electrons than

\mathrm{Fe}^{+2}.

View answer and explanation

Correct option: B

Both S-I and S-II are incorrect

The correct answer is B (Both S-I and S-II are incorrect) because Fe+3 is more stable than Fe+2 due to its half-filled d-orbital configuration, and it has more unpaired electrons.
