Given below are two statements: Statement I : The identification of Ni 2 + is carried out by dimethyl glyoxime in the presence of NH 4 OH . 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:
Options
- AStatement I is false but Statement II is true.
- BStatement I is true but Statement II is false.
- CBoth Statement I and Statement II are true.
- DBoth Statement I and Statement II are false.
Correct answer
B. Statement I is true but Statement II is false.
Step-by-step solution
Neutral dimethyl glyoxime does not act as ligand. When Ni 2 + reacts with dimethyl glyoxime in presence of NH 4 OH , it produce dimethyl glyoximate then it form rozy red ppt. Ni aq 2 + + 2 dmg - → Ni dmg 2 Rosy   red   ppt .
