Given below are two statements:
Statement (I): Dimethyl glyoxime forms a six membered covalent chelate when treated with NiCl₂ solution in presence of NH₄OH.
Statement (II): Prussian blue precipitate

Question

Given below are two statements:
Statement (I): Dimethyl glyoxime forms a six membered covalent chelate when treated with NiCl₂ solution in presence of NH₄OH.
Statement (II): Prussian blue precipitate contains iron both in (+2) and (+3) oxidation states.
Choose the most appropriate answer:

Canvas Classes · Accepted Answer

Strategy:
 Analyze the structure of the DMG-Ni complex and the composition of Prussian blue.

Step 1: Evaluate Statement (I)
Dimethylglyoxime (DMG) reacts with  to form a rosy red precipitate of .
This complex forms 5-membered chelate rings (Ni-N-C-C-N), not 6-membered rings.
Therefore, Statement I is False.

Step 2: Evaluate Statement (II)
Prussian blue is Iron(III) hexacyanidoferrate(II), formula .
The central iron within the coordination sphere is , and the outside iron is .
Therefore, Statem
