Coordination compounds have great importance in biological systems. In this context which of the following
statements is incorrect ?
In Fe(CO)5 the Fe-C bond possesses
Aqueous solution of Ni2+ contains [Ni(H2O)6]2+ and its magnetic moment is 2.83 B.M. When ammonia is added in it, comment on the magnetic moment of the solution, if coordination number remains same
Which of the following is correctly matched ?
In the compound,lithium tetrahydridoaluminate,the ligand is
The oxidation state of Fe in brown complex [Fe(H2O)5NO] SO4 is
A metal complex having composition Cr(NH3)4Cl2Br has been isolated in two forms X and Y. The form X reacts with AgNO3 to give a white precipitate, readily soluble in dilute aqueous ammonia, whereas Y gives a pale yellow precipitate soluble in concentrated ammonia. X and Y are respectively.
In the coordination compound, K4[Ni(CN)4], the oxidation state of nickel is
Cyanide ion is a very good complexing agent and also functions as a reducing agent. Hence may cyanide
complexes of metals are known. Addition of an aqueous solution of KCN to a solution of copper
sulphate yields a white precipitate which is soluble in excess of aqueous KCN to form the complex
