Why does the chromyl chloride test fail with `Br^(ɵ)` and `I^(ɵ)`?

Text Solution

AI Generated Solution

To understand why the chromyl chloride test fails with bromide (Br⁻) and iodide (I⁻) ions, we need to delve into the properties of the compounds formed during the test. ### Step-by-Step Solution: 1. **Understanding the Chromyl Chloride Test**: - The chromyl chloride test involves the reaction of halides (like Cl⁻, Br⁻, and I⁻) with chromyl chloride (CrO₂Cl₂) to form corresponding chromyl halides. 2. **Formation of Chromyl Bromide and Chromyl Iodide**: ...
