JEE Main 2026 Chemistry question

Consider the transition metal ions and and all form low spin octahedral complexes. The correct decreasing order of unpaired electrons in their respective d-orbitals of the complexes is

• (1)Cr^{3+} > Fe^{3+} > Co^{3+} > Mn^{3+}
• (2)Mn^{3+} > Fe^{3+} > Co^{3+} > Cr^{3+}
• (3)Fe^{3+} > Co^{3+} > Mn^{3+} > Cr^{3+}
• (4)Cr^{3+} > Mn^{3+} > Fe^{3+} > Co^{3+}Correct
