How many of the following salts contain a paramagnetic octahedral anion? K₃[CoF₆], K₃[Fe(CN)₆], K₄[Fe(CN)₆], K₂[PtCl₆], K₃[Cr(ox)₃], Na₃[Co(NO₂)₆], K₂[NiCl₄], K₄[Mn(CN)₆]
Answer:
4
Solution:
Paramagnetic octahedral anions: [CoF₆]³⁻ (4 unpaired), [Fe(CN)₆]³⁻ (1), [Cr(ox)₃]³⁻ (3) and [Mn(CN)₆]⁴⁻ (1). [Fe(CN)₆]⁴⁻, [PtCl₆]²⁻ and [Co(NO₂)₆]³⁻ are diamagnetic, and [NiCl₄]²⁻ is tetrahedral. Count = 4.
