Q. Assertion :A stable complex is formed when ethylene diamine (en) is added to [Ni(H2O)4]2+. Reason: (en) being a strong ligand replaces weak ligand H2O and thus, chelate is formed.
Q. Addition of excess aqueous ammonia to a pink coloured aqueous solution of MCl2.6H2O(X) and NH4Cl gives an octahedral complex Y in the presence of air. In aqueous solution, complex Y behaves as 1 :3 electrolyte. The reaction of X with excess HCl at room temperature results in the formation of a blue coloured complex Z. The calculated spin only magnetic moment of X and Z is 3.87 B.M., whereas it is zero for the complex Y. Among the following options, which statement(s) is/are correct?
