Given below are two statements:
Statement I: The identification of $$Ni^{2+}$$ is carried out by dimethyl glyoxime in the presence of $$NH_4OH$$.
Statement II: The dimethyl glyoxime is a bidentate neutral ligand.
In the light of the above statements, choose the correct answer from the options given below:

We need to evaluate both statements about the identification of $$Ni^{2+}$$ using dimethyl glyoxime (DMG).

Statement I says that the identification of $$Ni^{2+}$$ is carried out by dimethyl glyoxime in the presence of $$NH_4OH$$. This is true. When DMG is added to a solution containing $$Ni^{2+}$$ ions in the presence of ammonium hydroxide (which provides a slightly basic medium), a bright rose-red precipitate of nickel dimethylglyoximate is formed. This is a classic qualitative test for nickel(II) ions.

Statement II says that dimethyl glyoxime is a bidentate neutral ligand. DMG is indeed bidentate, coordinating through its two nitrogen atoms of the oxime groups. However, when DMG coordinates with $$Ni^{2+}$$, the hydroxyl protons of the oxime groups are lost, meaning the ligand acts as an anionic (monoanionic) ligand, not a neutral one. Therefore, Statement II is false because DMG functions as a bidentate anionic ligand, not a neutral ligand.

Since Statement I is true but Statement II is false, the correct answer is option (2).
