The Total solution for NCERT class 6-12
Amongst the following, the most stablecomplex is
(i)┬а[Fe(H2O)6]3+┬а ┬а ┬а┬а(ii)┬а[Fe(NH3)6]3+┬а ┬а ┬а ┬а ┬а ┬а┬а(iii)┬а[Fe(C2O4)3]3тИТ┬а ┬а ┬а ┬а ┬а ┬а ┬а ┬а┬а(iv)┬а[FeCl6]3тИТ
Weknow that the stability of a complex increases by chelation. Therefore, themost stable complex is [Fe(C2O4)3]3тИТ.
