Chemistry Question on Halides and Hydrides of alkali
Mercury is not considered as transition metal however it has tendency to react with chlorine to form chlorides X and Y. X reacts with Kl to give red ppt while Y doesn't react. On the contrary, Y react with NH4OH to give a black ppt. Predict the formula of X and Y :
A
X=Hg2Cl2, Y =HgCl
B
X=Hg2Cl2, Y =HgCl2
C
X=HgCl, Y =HgCl2
D
X=HgCl2, Y =Hg2Cl2
Answer
X=HgCl2, Y =Hg2Cl2
Explanation
Solution
The correct option is (D) : X=HgCl2, Y =Hg2Cl2
