Identify the correct statements from the following
- A (I) \(\mathrm{Au}\) is soluble in aqua regia but not \(\mathrm{Pt}\)
- B (II) Among the oxoacids of chlorine highest oxidation state possible for chlorine is +7
- C (III) Among the hydrogen halides lowest boiling point is for \(\mathrm{HCl}\)
- D (IV) The order of stability of oxides of halogens is \(\mathrm{Cl}>\) \(\mathrm{Br}>\mathrm{I}\)
Answer & Solution
Correct Answer
(B) (II) Among the oxoacids of chlorine highest oxidation state possible for chlorine is +7
Step-by-step Solution
Detailed explanation
Statement (I) is incorrect because both, \(\mathrm{Au}\) and \(\mathrm{Pt}\) dissolve in aqua regia and form soluble compounds \(\mathrm{HA}_4 \mathrm{Cl}_4\) and \(\mathrm{H}_2 \mathrm{PtCl}_6\). Statement (IV) is incorrect as the correct order of the stability of the oxides of…
