Detailed Solution

The above statement is false.
Alkaline KMnO4 acts as an oxidising agent.
Oxidising agents act by accepting electrons to oxidise other substances and reduce themselves.. Oxidising agents are also known as electron acceptors.
The reaction is given as follows:
 C2H5OH +Alkaline KMnO4 CH3COOH                                              When ethanol is reacted with alkaline KMnO4 . It results in the formation of ethanoic acid. In this, alkaline KMnO4  acts as a strong oxidising agent that converts primary alcohol into a carboxylic acid and increases its oxidation state by four. In order to increase the speed and selectivity of oxidation, a very strong basic condition is used.
The correct statement would be that alkaline KMnO4 acts as an oxidising agent.
