NEET 2007 Chemistry question
The d electron configurations of , , and are , , and respectively. Which one of the following aqua complexes will exhibit the minimum paramagnetic behaviour? (Atomic number. Cr = 24, Mn = 25, Fe = 26, Ni = 28)
Answer: (4)
Solution
is a weak-field ligand, so the complexes are high spin and electrons pair only when forced to. Number of unpaired electrons: () = 4; () = 5;
