Statement (I) : Dimethyl glyoxime forms a sixmembered covalent chelate when treated with

Question

Given below are two statements : 

Statement (I) : Dimethyl glyoxime forms a sixmembered covalent chelate when treated with \(NiCl_2\) solution in presence of \(NH_4OH\). 

Statement (II) : Prussian blue precipitate contains iron both in (+2) and (+3) oxidation states. 

In the light of the above statements, choose the most appropriate answer from the options given below: 

(1) Statement I is false but Statement II is true 

(2) Both Statement I and Statement II are true 

(3) Both Statement I and Statement II are false 

(4) Statement I is true but Statement II is false

Answer 1
