Question:
Out of Ti3+, Cr3+, Fe2+ and Ni2+ ions, the one which is the most stable ion in aqueous solution is:
Out of Ti3+, Cr3+, Fe2+ and Ni2+ ions, the one which is the most stable ion in aqueous solution is:
Show Hint
Half-filled and fully filled d-orbital configurations offer extra stability in transition metal ions.
Updated On: Jun 24, 2025
- Ti3+
- Cr3+
- Fe2+
- Ni2+
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Cr3+ (3d3) has a half-filled t2g configuration in an octahedral field, which imparts exceptional stability due to symmetrical distribution and exchange energy. Hence, Cr3+ is the most stable in aqueous medium.
