Question

Addition of excess aqueous ammonia to a pink coloured aqueous solution of $M C l_{2} . 6 H_{2} O (X)$ and $N H_{4} C l$ 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 complex Y.

Among the following options, which statement is incorrect?

Options:

Answer:

B

Solution:

X and Z are in equilibrium at $0^{o} C$ , equilibrium is shifted towards X, making colour of solution pink.
