MnCr2O4 isa)normal spinel with total CFSE of −15.5 Dqb)inverse s...
Explanation:
Normal Spinel vs Inverse Spinel:
- In a normal spinel structure, the divalent cations occupy the tetrahedral sites while the trivalent cations occupy the octahedral sites.
- In an inverse spinel structure, the divalent cations occupy both the tetrahedral and octahedral sites while the trivalent cations occupy only the octahedral sites.
Calculation of CFSE:
- For MnCr2O4, the oxidation state of Mn is +2 and that of Cr is +3.
- The crystal field stabilization energy (CFSE) is calculated based on the number of electrons in the d orbitals and the type of ligand field.
- The total CFSE for MnCr2O4 in a normal spinel structure is -24 Dq, where Dq is the crystal field splitting energy.
- This value indicates that the total energy stabilization due to crystal field effects is -24 times the energy of one Dq.
- In an inverse spinel structure, the total CFSE would be different due to the different arrangement of cations in the crystal structure.
Therefore, option C is correct as MnCr2O4 is a normal spinel with a total CFSE of -24 Dq.
