Write the IUPAC name and describe the magnetic behaviour (diamagnetic or paramagnetic) of the following coordination entities : `[Cr(H_2O)_2 (C_2O_4)_2]^(-)`

Text Solution

Verified by Experts

IUPAC Name : Diaquadioxalatochromate (III) ion.
Magnetic behaviour : Electronic configuration of `Cr^(3+) " is " 3d^3`. Unpaired electrons (n) = 3.
Therefore, complex ion is paramagnetic due to the presence of three unpaired electrons.
