Propene + COLD Potassium Permanganate

A reaction between Propene and COLD Potassium Permanganate would lead to the formation of 1,2 propandiol, right ?

yes, would be nice if you know the Mn product too to differentiate it from that done under alkaline or neutral condition.

in acidic condition, the manganese turns from purple to colourless, Mn(VII) --> Mn(II)

in basic/neutral, the manganese turns green due to Mn(VII) ---> Mn(VI) and then stepwise, further to dark brown Mn(IV)oxide, MnO2.

you can write equations to depict this to convince yourself, but in both cases, you'd get the diols.
