WebHowever, ketones can be oxidized to various types of compounds only by using extremely strong oxidizing agents. Typical oxidizing agents for aldehydes include either potassium permanganate (KMnO 4) or potassium dichromate (K 2 Cr 2 O 7) in acid solution and Tollens reagent. Peroxy acids, such as peroxybenzoic acid: WebApr 26, 2012 · Alkyl groups are usually fairly resistant to oxidation. However, when they are attached to a benzene ring, they are easily oxidised by an alkaline solution of potassium manganate(VII) (potassium permanganate). Methylbenzene is heated under reflux with a solution of potassium manganate(VII) made alkaline with sodium carbonate. WebPotassium permanganate (KMnO 4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO 4 oxidizes primary alcohols to carboxylic acids very efficiently. fallen shoes amazon
