    It is assumed that hot alkaline KMnO4 is being used. 1,4-Cyclohexadiene on reaction with KMnO4 will break down to a dicarboxylic acid prop-1,3-dioic acid (malonic acid). Malonic acid readily losses CO2 to give acetic acid.

    HO.CO. CH2.CO.OH ---------> CO2 + CH3.COOH

    4-Methylcyclohexene will give a 1,6-dicarboxylic acid. The breakdown of the molecule wil be at C1-C2 double bond. The product will be 3-methylhex-1,6-dioic acid.
