Answer 1

Hey Shantanu,

Following are the chemical formulas for required complexes.

(i) Tetraamminediaquacobalt(III) chloride

[CO(H2O)2(NH3)4]Cl3

(ii) Potassium tetracyanonickelate(II)

K2[Ni(CN)4]

(iii) Tris(ethane−1,2−diamine) chromium(III) chloride

[Cr(en)3]Cl3

(iv) Amminebromidochloridonitrito-N-platinate(II)

[Pt(NH3)3BrCl(NO2)]-

(v) Dichloridobis(ethane−1,2−diamine) platinum(IV) nitrate

[PtCl2(en)2](NO3)2

(vi) Iron(III) hexacyanoferrate(II)

Fe4[Fe(CN)6]3
