A, B and C are three complexes of chromium (III) with the empirical formula H_(12)O_(6)Cl_(3)Cr. All the three complexes have water and chloride ion as ligands. Complex A does not react with concentrated H_(2)SO_(4), whereas complexes B and C lose 6.75% and 13.5% of their original weight, respectively, on treatment with concentrated H_(2)SO_(4). Which type of isomerism is possible in complex C?

1.	A, B and C are three complexes of chromium (III) with the empirical formula H_(12)O_(6)Cl_(3)Cr. All the three complexes have water and chloride ion as ligands. Complex A does not react with concentrated H_(2)SO_(4), whereas complexes B and C lose 6.75% and 13.5% of their original weight, respectively, on treatment with concentrated H_(2)SO_(4). Which type of isomerism is possible in complex C?
Answer» Geometrical Hydration Co-ordnation Both (a) and (b) SOLUTION :`C implies [Cr(H_(2)O)_(4)Cl_(2)].Cl.2H_(2)O` can exhibit geometrical and HYDRATE isomerism.
