1.	(a) (i) A solution of [Co(NH_(3))_(4)I_(2)]Cl_(2) when treated with AgNO_(3) gives a white precipitate. What should be the formula of isomer of the dissolved complex that gives yellow precipitate with AgNO_(3). What are the above isomers called? (ii) Write the following in the complex [Cr("en")_(3)] [CrF_(6)] (i) Type of complex (ii) Ligands (iii) central metal (iv) Oxidation state of central metal (v) IUPAC name
Answer» SOLUTION :(a) (i) 1 A solution of `[Co(NH_(3))_(4)I_(2)]Cl` when treated with `AgNO_(3)` gives a white precipitate. Because `Cl^(-)` ION is COUNTER ion. 2. Formula of isomer of the dissolved complex that give YELLOW precipitate with `AgNO_(3) " is " [Co(NH_(3))_(4)Cl] I` because `I^(ө)` is counter ion 3. `[Co(NH_(3))_(4) I_(2)] Cl and [Co(NH_(3))_(4)Cl I]` I both are ionisation isomers (ii)
