Co-ordiantion compounds show structural isomerism and it is different

1.	Co-ordiantion compounds show structural isomerism and it is different from the nature of the isomerism which we generally come across in organic compounds. The co-ordination and linkage isomers depending upon their upon the number of ions which they furnish upon dissociation in aqueous solution . The isomers belonging to a particular type can also be distinguished from each structural isomerism, the co-ordination compounds are also involved in geometrical and optical isomerism. Whereas optical octahedral and square planar complexes can exhibit geometrical isomerism. Which one is the most likely structure of `` if 1/3 of the total chloride in the compound is precipitated by adding `` solution ?A. `CrCl_(3).6H_(2)O`B. `[Cr(H_(2)O)_(3)]Cl_(3)](H_(2)O)_(3)`C. `[Cr(H_(2)O)_(4)Cl_(2)]Cl.2H_(2)O`D. `[Cr(H_(2)O)_(5)Cl]Cl_(2).H_(2)O`
Answer» Correct Answer - c is the correct answer because out of the three Cl atoms present, only one represents primary valency (ionisable) .
