Question

 Name the following or write the formula:

[FeBr₂(C₂O₄)₂]³⁻

Diaquadichloridodinitrito-κO-rhenate(III) ion

Bromidochloridofluoridoiodidolead(IV)

[W(CO)₃(NO₃)₂(SO₄)]⁺

Answer 1

1. given

[FeBr₂(C₂O₄)]^3-

^{here, 2-bromine and 2 oxalate}

^{x+2×((-1)+2(-1)+2(-1)=-3}

^×=+3

^{IUPAC will be: Dibromo bis(oxalate)ferrate(III)}

^{2. Diaquadichloridodinitrito-κO-rhenate(III) ion}

^{[2 water molecule, 1 cl and 1 nitro group]}

formula: [W(H₂O)₂Cl(ONO)]

3. Bromidochloridofluoridoiodidolead(IV)

here, bromine-1, chlorine-1, fluorine-1, and iodine-1

formula:[pb(Br)(Cl)(F)(I)]

4.[W(CO)₃(NO₃)₂(SO₄)]⁺

^{x+3(0)+2(-1)+1(-2)=+1}

^x=+5

^{formula: Tricorbonyldinitrate Sulphate tungsten(v)}
