Not sure “half help” can help… I recall organic alcohols oxidises to organic acid when left in air
(Beer will turn sour when left in air, being oxidised by O2) – a concept that always sticks in my brain…
So propanol should be oxidised to propanoic acid (CH3CH2COOH)
Exact reduction changes to potassium maganate (VII) (purple potassium permaganate), I’m not sure.
Maybe expert can give equation.
