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:
- A Statement \(I\) is false but Statement \(II\) is true.
- B Both Statement \(I\) and Statement \(II\) are false.
- C Statement \(I\) is true but Statement \(II\) is false.
- D Both Statement \(I\) and Statement \(II\) are true.
Answer & Solution
Correct Answer
(C) Statement \(I\) is true but Statement \(II\) is false.
Step-by-step Solution
Detailed explanation
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. \(Ni ^{2+}{ }_{( aq )}+2 dmg ^{-} \rightarrow\left[ Ni ( dmg )_{2}\right]\)…
