Chromyl Chloride test is not given by chlorides of mercury, tin, silver, lead and antimony because they are covalent.
Explanation:
- To detect the presence of chlorine ions in a compound Chromyl chloride test is used.
- The principle involved is that ionci compound shows positive reaction for chromyl chloride test.
- If the substance contains chlorine, it shows a positive reaction by forming chromyl chloride, whereas if the chlorine is absent, it doesn't show a positive reaction.
- In the case of chlorides of mercury, tin, silver, lead and antimony due to their covalent nature, it is very difficult for the displacement of chlorine ions from them.
- Thus they don't give Chromyl chloride.
