Title: Hydrocarbon Reaction Question
Post by: iamash on January 07, 2014, 07:07:31 PM

Hey!
I'm going through my chemistry textbook and found this question:
Write the equation of the following: the reaction of propene with potassium permanganate (KMnO4).

I'm not sure how they'd react; would it be an addition reaction (if so, how would permanganate ion make a covalent bond with the carbon). Or perhaps its a substitution reaction where the K replaces an H atom which then bonds with permanganate to form HMnO4.

Does anyone have any idea of how they'd react?
Thanks, Ash! ;D

The oxidation number of the manganese ion in potassium permanganate is +7.
