Question

Match List - I with List - II. Match the number of d-electrons and CFSE in tetrahedral complexes (ignore pairing) 

Choose the correct answer from the options given below : 
 

• A. A-III, B-I, C-IV, D-II
• B. A-III, B-I, C-II, D-IV
• C. A-IV, B-I, C-II, D-III
• D. A-II, B-III, C-IV, D-I

Hint:

Remember the inversion between octahedral and tetrahedral field splitting: Octahedral is $t_{2g}$ (lower, -0.4) and $e_g$ (upper, +0.6). Tetrahedral is $e$ (lower, -0.6) and $t_2$ (upper, +0.4). Tetrahedral complexes are essentially always high-spin!
