QAIPMT-2008-Ch-2194: NEET 2008 Chemistry - Class 12 AIPMT-2008-Ch-2194 Solution: In which of the following coordination entities the magnitude…

In which of the following coordination entities the magnitude of Δo\Delta_o (CFSE in octahedral field) will be maximum? (At. No. Co = 27)

Multiple Choice Options

  • A [Co(CN)6]3−[Co(CN)_6]^{3-}
  • B [Co(C2O4)3]3−[Co(C_2O_4)_3]^{3-}
  • C [Co(H2O)6]3+[Co(H_2O)_6]^{3+}
  • D [Co(NH3)6]3+[Co(NH_3)_6]^{3+}

Step-by-Step Verified Solution

In all the given options the central metal atom is same and contain same number of d electrons. Thus, CFSE is decided by ligands. In case of strong field ligand, CFSE is maximum, CN � is a strong field ligand hence is [Co(CN) 6 ] 3� so CFSE is maximum.
