Which of the following complexes may show atleast three type of isomerism, namely ionisation, hydrate and linkage ?

Options

A. `[Co(H_(2)O)_(5)Cl]S_(2)O_(3)`
B. `[Ag(NH_(3))_(2)][Ag(CN)_(2)]`
C. `[Cr(H_(2)O)_(5)(NO_(2))]SO_(4)`
D. `[Ni(H_(2)O)_(6)]SO_(4)`

Answer

C

Explanation

(a) `[Co(H_(2)O)` : Show ionisation and hydrate
(b) `[Ag(NH_(3))_(2)][Ag(CN)_(2)]` : Show linkage
(c ) `[Cr(H_(2)O)_(5)(NO_(2))] SO_(4)` : Show ionisation, hydrate and linkage
(d) `[Ni(H_(2)O)_(6)]SO_(4)` : Show linkage and hydrate
