Detailed Solution

The above statement is true.
An alkaline solution of cold potassium permanganate is called Baeyer's reagent ( KMnO4 ). Alkyne and alkene are examples of unsaturation-containing molecules that can be detected using the alkaline potassium permanganate test in qualitative chemical analysis. In these types of reactions, potassium permanganate acts as an oxidising agent. Thus, potassium permanganate is used in qualitative organic analysis to test for the presence of unsaturation in organic compounds.
