Cis-plaitn
Zeisse’s sale
Both (a) and (b)
None of these
Which has maximum EAN of the underlined atoms? (Cr = 24, Co = 27, Fe=26, Ni=28)
[Cr(EDTA)]-
[Co(en)3]3+
[Fe(C2O4)3]3-
[Ni(CN)4]2-
Among Ni(CO)4, [Ni(CN)4]2- and NiC12-4:
Ni(CO)4, and [Ni(CN)4]2- are diamagnetic and NiC12-4 is paramagnetic
Ni(CO)4, and NiC12-4 are diamagnetic and [Ni(CN)4]2- are paramagnetic
Ni(CO)4, is diamagnetic and [Ni(CN)4]2- and NiC12-4 are paramagnetic
NiC12-4 and [Ni(CN)4]2- are diamagnetic and Ni(CO)4 is paramagnetic
While Ti3+, V3+, Fe3+ and Co2+ afford a large number of tetrahedral complexes, Cr3+ never does this, the reason being:
Cr3+ forces high crystal field splitting with a varieties of ligands
Crystal field stabilization energy in octahedral vis-a-vis tetrahedral Cr3+ system plays the deciding role
The ionic radius of Cr3+ is the largest among the other M3+ ions mentioned
Electronegativity of Cr3+ is the largest among these trivalent 3d-metals and so chromium prefers to be associated with as many ligands as its ionic radius permits
Match the geometry(given in column A) with the complexes (given in column B) in: Geometry:A I: Octahedral II: Square planar III: Tetrahedral Complex: B P: [Ni(CN)4]2- Q: Ni(CO)4 R: [Fe(CN)6]4- I II III I II III

Estimating the concentration of iron
Measuring the concentration of CN-
Measuring the magnetic moment
Thermally decomposing the compound
