(a)

• We have tetrahydroxozincate\(\left( {{\bf{II}}} \right)\)ion from which we could see that we have\({\bf{4}}\)monodentate hydroxyl ligands inside the coordination sphere.
• It means that the coordination number of the central metal ion\({\rm{Zn}}\)is\({\bf{4}}\).
• Hence, the formula of ion is\({\left( {{\rm{Zn}}{{({\rm{OH}})}_4}} \right)^{2 - }}\)

(b)

• We have\(hexacyanopalladate(IV) ion\)ion from which we could see that we have\(6\)monodentate cyano ligands inside the coordination sphere.
• It means that the coordination number of the central metal ion\({\rm{Pd}}\)is\(6\).
• Hence, the formula of ion is\({\left( {Pd{{(CN)}_6}} \right)^{2 - }}\)

(c)

• Here, we have\(dichloroaurate(I) ion\)from which we can see that we have\( {\bf{2}} \)monodentate ligands inside the coordination sphere.
• It clearly means that the coordination number of the central metal ion\({\bf{Au}}\)is\( {\bf{2}} \).
• The formula of the ion is\({\left( {AuC{l_2}} \right)^ - }\)

(d)

• We have\(diamminedichloroplatinum(II)\)from which we can see that we have\({\bf{4}}\)monodentate ligands inside the coordiantion sphere.
• It means that the coordination number of the central metal ion\( {\bf{Pt}}\)is\({\bf{4}}\).
• The formula of the compound is\(\left( {{\rm{Pt}}{{\left( {{\rm{N}}{{\rm{H}}_3}} \right)}_2}{\rm{C}}{{\rm{l}}_2}} \right)\)

(e)

• We have\(potassium diamminetetrachlorochromate(III)\)from which we can see that we have\(6\)monodentate ligands (\({\bf{4}}\)chloride and\( {\bf{2}} \)amine ) inside the coordination sphere.
• It clearly means that the coordination number of the central metal ion\( {\rm{Cr}}\)is\(6\)
• The formula of the compound is\({\rm{K}}\left( {{\rm{Cr}}{{\left( {{\rm{N}}{{\rm{H}}_3}} \right)}_2}{\rm{C}}{{\rm{l}}_4}} \right)\)

(f)

• We have\(hexaamminecobalt(III) hexacyanochromate(III)\)from that we can see that we have\(6\)monodentate ligands, in both cases, inside the coordination sphere.
• It gives us a clue that the coordination number of the central metal ion\({\bf{Co}}\)and\({\bf{Cr}}\)is\(6\)
• The formula of the compound is\(\left( {{\rm{Co}}{{\left( {{\rm{N}}{{\rm{H}}_3}} \right)}_6}} \right)\left( {{\rm{Cr}}{{({\rm{CN}})}_6}} \right)\)

(g)

• We have\(dibromobis(ethylenediamine) cobalt(III) nitrate\)and from that we can see that we have\( {\bf{2}} \)monodentate ligands (\( {\bf{2}} \)bromide ) and\( {\bf{2}} \)bidentate ligands (en) inside the coordination sphere.
• It leaves us a clue that the coordination number of the central metal ion\({\bf{Co}}\)is\(6\).
• The formula of the compound is\( \left( {{\rm{CoBr}}{r_2}{{(en)}_2}} \right){\rm{N}}{{\rm{O}}_3}\)
