Question

Baeyer's reagent is:

• A. Alkaline ${\mathrm{KMnO}}_4$ solution
• B. Acidic ${\mathrm{KMnO}}_4$ solution
• C. Neutral ${\mathrm{KMnO}}_4$ solution
• D. Aqueous bromine solution

Answer 1

The correct option is A

Alkaline ${\mathrm{KMnO}}_4$ solution

The explanation for the correct answer:

Baeyer's reagent:

1. This reagent is basically the cold Potassium permanganate solution that must be alkaline in nature.
2. Actually, it is a strong oxidizing agent that can be further utilized for the purpose of organic analysis.
3. This is a violet color solution.
4. In this, the alkaline ${\mathrm{KMnO}}_4$ is used as it is the oxidizing agent so can be used just to oxidize alcohol to the acid.
5. And as soon as this solution interacts with the double bond compound, the color will get disappear and then become colorless.
6. The use of this reagent can be used to indicate the presence of unsaturated hydrocarbon in the compounds.
7. This Baeyer's reagent can also be used for various purposes: wound cleaning, medication, in chemical laboratories, etc.
8. Reaction to the use of this reagent:

Hence, the correct option is (A): Alkaline ${\mathrm{KMnO}}_4$ solution.
