diammine (ethylenediamine) nitratoruthenium (III)

diammine (ethylenediamine) ruthenium (II) nitrate

diamminebis (ethylenediamine) ruthenium (III) nitrate

(ethylenediamine) diammineruthenium (II) nitrate

Answer is:

diammine (ethylenediamine) ruthenium (II) nitrate

225) Which one of the following is true?

The charge on the complex ion in K₂[PtCl₄] is +2

The coordination number of Hg in [Hg(en)₂]²⁺ is 4

The oxidation number of Fe in [Fe(CN)₆]⁴⁻ is +6

In transition metal complexes, ligands act as Lewis acid

Answer is:

The coordination number of Hg in [Hg(en)₂]²⁺ is 4

226) In the silver plating of copper, K[Ag(CN)₂] is used instead of AgNO₃. The reason is:

Less availability of Ag⁺ ions, as Cu cannot displace Ag from [Ag(CN)₂] ion

More voltage is required

A thin layer of Ag is formed on Cu

Ag⁺ ions are completely removed from solution

Answer is:

Less availability of Ag⁺ ions, as Cu cannot displace Ag from [Ag(CN)₂] ion

227) Tetrahedral complexes of the types of [Ma₄] and [Ma₃b] (M = metal; a, b = achiral ligands) are not able to show optical isomerism because:

These molecules have non super imposable mirror images

These molecules posses a center of symmetry

These molecules possess a plane of symmetry and hence, are achiral

These molecules possess C_n axis of symmetry

Answer is:

These molecules possess a plane of symmetry and hence, are achiral
