identify the given pairs of coordination complexes which exhibit the same kind of isomerism among the following?

(a) [Ni(NH2-CH2COO)2] and [Co(NH3)2Cl2(en)]+

(b) [Cr(H2O)6]Cl3 and [Co(NH3)4Br2]Br.H2O

( c) [Cr(NH3)5Cl)]Cl2 and {Cr(NH3)4Cl2]Cl

(d) [Co(en)3]3+ and [Co(NH3)3Cl3]

Option c is the right answer these pair show solvate isomerism. Because the compound showing solvate isomerism ate different one in the no. of solvent molecules present as ligand. As in the case of given Pair solvent molecule is Cl. In given pair of compounds no. of Cl molecules are same but the moleculesof Cl present as ligand are greater in Second than that is first.
