Identify the incorrect statement in the following

The calculated spin-only magnetic moments (BM) of the anionic and cationic species of $$[Fe(H_2O)_6]_2$$ and $$[Fe(CN)_6]$$, respectively, are:

$$\left[ Cr\left( { H }_{ 2 }O \right) _{ 6 }{ Cl }_{ 3 } \right] $$ has a magnetic moment of 3.83 BM. The correct distribution of 3d electrons in the chromium atom in the complex is:

For which of the following elements all of its existing ion, $$M^{x+}$$, will be diamagnetic?

Match the catalysts (Column I) with products column (II)

Consider the hydrates ions of $$Ti^{2+}, V^{2+}, Ti^{3+}$$ and $$Sc^{3+}$$. The correct order of their spin-only magnetic moments is:

In the hydrogenenation of oil :-

Photochromic glass, used for sunglasses, darkens when exposed to bright light and becomes
more transparent again when the light is less bright. The darkness of the glass is related to the
concentration of silver atoms.
The following reactions are involved.
reaction 1 $$Ag^{+}  + Cl^{-}\rightleftharpoons Ag + Cl$$
reaction 2 $$Cu^{+} + Cl \rightarrow Cu^{2+} + Cl^{-}$$
reaction 3 $$Cu^{2+} + Ag \rightarrow Cu^{+}  + Ag^{+}$$
Which statement about these reactions is correct?

The INCORRECT statement is:

Select the paramagnetic complex compound.
