parts. Write the formulas for each of the following ions and compounds (a)
bis(ethylenediamine)dichlorochromium(III) Crfen)2Cl2] (b) pentacarbonyliron(0) (c) potassium
tet racyanocuprat e(II) (d) tetraammineaquochlorocobalt() chloride 2 Report problem
Solution
Bis(ethylenediamine)dichlorochromium(III)
the metal atom is Cr
bidentatate ligand = ethylene diamine
mono dentate ligand = chloro
Formula: [Cr(en)2Cl2]^+
Pental carbonyl Iron(0)
here penta indicates five in number and the metal is iron
Formula: Fe(CO)5
Potassium teracyanocuprate(II)
tetra indicate four in number
Formula: K2[Cu(CN)4]
Tetrammineaquochlorocobalt(III)chloride
aquo indicates H2O

2.
Ammine indicats NH2 ligand
Formula: [Co.H2O.Cl(NH2)4]Cl2
