If there is one alkyl group and one hydrogen at one end of the bond, that part of the molecule will give a carboxylic acid. © Jim Clark 2003 (last modified March 2016). Isomer A gives a ketone (propanone) and carbon dioxide. Working back from the results helps you to work out the structure of the alkene. Concentrated sulfuric acid dehydrates potassium permanganate to the incredibly unstable manganese heptoxide.Adding a few drops of glycerol (glycerin) to potassium permanganate creates an intense flame hot enough to light thermite and pyrotechnics. The acid structure has been turned around slightly to make it look more like the way we normally draw acids, but the net effect is that an oxygen has been slotted in between the carbon and hydrogen. As an Antidote. The potassium permanganate has again, here, released oxygen and become potassium manganate, transforming from purple through blue to green and finally brown. The compound has a bright, red-orange appearance. That means that the reaction won't stop at this point unless the potassium manganate(VII) solution is very dilute, very cold, and preferably not under acidic conditions. Only 12 left in stock - order soon. It has a sweet flavour. Potassium permanganate and manganese dioxide. Dilute solutions of KMnO4 convert alkenes into diols (glycols). It can also be made by reacting hot potassium permanganate with potassium hydroxide. Potassium permanganate and potassium dichromate are very common in laboratories because we commonly use them in titration procedures. The overall effect of the potassium manganate(VII) on this kind of alkene is therefore: Obviously, if there was a hydrogen atom attached to both carbons at the ends of the carbon-carbon double bond, you would get two carboxylic acid molecules formed - which might be the same or different, depending on whether the alkyl groups were the same or different. The evaporation of water from this solution gives dark purple, glistening crystals.
