formula of chloro cyano nitro triamine cobalt
Answers
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]+
