Question

formula of chloro cyano nitro triamine cobalt​

Answer 1

Answer:

Rules for preparing formula of Coordination compound from IUPAC name:

1

Ex.1 )  Tetra amine chloro nitro Cobalt (III) nitrate

Anion –     NO3–

Cation –  [Co Cl (NO2) (NH3)4]x

x = oxidation number of Co + oxidation number of Cl + oxidation number of NO2 + 4 x oxidation number of NH3

= 3 +1 (-1) +1(-1) +4 x 0

x = +1

Complex cation-   [Co Cl (NO2) (NH3)4]+

Complex compound –   [Co Cl (NO2) (NH3)4] NO3

Ex.2 )  Hexa aqua  Iron  (II) sulphate

Anion –     SO42-

Cation –  [Fe (H2O)6]x

x = oxidation number of Fe  + 4 x oxidation number of H2O

= 2 +6 x 0

x = +2

Complex cation-   [Fe (H2O)6]++

Complex compound –   [Fe (H2O)6]SO4

Ex.3 )  Penta amine  Nitrito   Cobalt (III) chloride

Anion –     Cl–

Cation –  [Co  (ONO) (NH3)5]x

x = oxidation number of Co + oxidation number of ( ONO) + 5 x oxidation number of NH3

= 3 +1 (-1)  + 5 x 0

x = +2

Complex cation-   [Co  (ONO) (NH3)5]++

Complex compound –   [Co  (ONO) (NH3)5] Cl2

Ex.4 )  Tetra aqua oxalato Iron  (III) chloride

Anion –     Cl–

Cation –  [Fe (H2O)4 (C2O4]x

x = oxidation number of Fe +  4 x oxidation number of H2O + oxidation number of C2O4

= 3  +4 x 0 +1 (-2)

x = +1

Complex cation-   [Fe (H2O)4 (C2O4]+
