Question

The pair in which both species have same magnetic moment is -, [ Cr ( H 2 O ) 6 ] 2 + , [ Co Cl 4 ] 2 -, [ Cr ( H 2 O ) 6 ] 2 + , [ Fe ( H 2 O ) 6 ] 2 +, [ Mn ( H 2 O ) 6 ] 2 + , [ Cr ( H 2 O ) 6 ] 2 +, [ Co Cl 4 ] 2 - , [ Fe ( H 2 O ) 6 ] 2 +

[ Cr ( H 2 O ) 6 ] 2 + have C r 2 + C r 2 + = 3 d 4 4 s ° (four unpaired electrons) F e 2 + = 3 d 6 4 s ° (in presence of weak ligand also have four unpaired electrons)
