Q.19)
(a) Cr2+(d4 system):- It is a high spin complex due weak field ligand. So it is labile complex that means rate of exchange of water takes place rapid.
(b).Ru2+(d6 system):- It is low spin complex due to strong field ligand. So it is inert complex that means rate of exchange of ligand is very slow.
