CrCl_(3).6H_(2)O" exists in different isomeric forms which show different colours like violet and green.This is due to "

Assertion : H_(2) exists in two isomeric forms known as ortho and para forms Reason : The ortho and para H_(2) differ in the spin of theire electron.

The existence of two different coloured complexes of [Co( NH_3)_4 Cl_2]^+ due to

The complex, [Co(NH_(3))_(4)Cl_(2)]^(+) is known to exist in two different coloured forms. This is due to

coordination compounds often show various types of isomerism. The isomerism can be categorized in two main types (a) structural isomerism (b) stereo or space isomerism Structural isomerism arises due to the difference in structures of coordination-sempounds while stereo or space isomerism arises on account of the different positions and arrangements of ligands (atoms or groups) in space around the metal lonStructural isomerism can be classified in following types (i) tonization isomers- which give different ions in solution, e.g. [CoBr(NH_(3))_(5)]]SO_(4) and [Co(SO_(4))_(5)(NH_(3))_(5)]Br Hydrate isomers which differ in H_(2)O as ligand or as hydration, e.g. [Cr(H_(2)O)_(5)]CI_(2)(H_(2)O)]Cl_(2).H_(2)O[CrCl_(2)(H_(2)O)]CI.2H_(2)O (iii) Linkage isomers, which differ in atom linked to 'metal atom, e.g. [CO(NO_(2))(NH_(3))_(5)]^(2+) and CO(ONO)(NH_(3))_(6)]^(2+) Coordination isomers- which involve interchange of ligands, e.g. [Co(NH_(3))_(6)] [Cr(CN)_(6)] and [Cr(NH_(3))_(6)] [Co(CN)_(6)] (v) Coordination position isomerism-which arises in the bridged complexes due to the difference in the attachment of ligands with the metal atoms Qcoordinate isomerism 33. How many hydrate isomers are possible with the formulae CrCl_(3).6H_(2)O

HgO is prepared by two different methods: one shows yellow colour while the other shows red colour. The difference in colour is due to difference in
