Question

a) For the complex [Fe(H2O)6]3+, write the hybridization,magnetic character and spin of the complex.(At.number: Fe=26).

b) Draw one of the geometrical isomers of the complex [Pt(en)2Cl2]2+ which is optically inactive.

Answer

i) Fe exists in the +3 oxidation state i.e, in d5 configuration.Since water is the weak ligand, therefore, there is no paired electron. Hence it is strongly paramagnetic and high spin.  
Hybridization sp3d2.
ii)
