WebDiana Sierra U Pre-Lab Chapter 15: Oxidation of an Aromatic Side Chain: Identification of an Unknown Chlorotoluene Purpose The purpose of this experiment is to use alkylbenzenes to undergo the oxidation process which will convert into a carboxylic acid that will get attached to the aromatic ring. Introduction In this experiment, we will discover the identity of one of … WebApr 25, 2012 · Some general information on side-chain oxidation in alkylbenzenes is available at Chemguide: An alkylbenzene is simply a benzene ring with an alkyl group attached to it. Methylbenzene is the simplest alkylbenzene. Alkyl groups are usually fairly resistant to oxidation.

WebAug 9, 2024 · To my knowledge, side chain oxidation with KMnO4 occurs only when a benzylic hydrogen is present. However this doesn't contain a benzylic hydrogen and hence according to me it wouldn't give any reaction. However the answer in my book states that Phenylacetylene will be oxidized to benzoic acid. WebJul 1, 2024 · The term side-chain oxidation is also commonly used. In alkylbenzenes, the carbon atom which is attached to the aromatic ring is particularly reactive. Reactions taking place at this carbon atom are said to occur at the benzylic position. Benzylic halides undergo the typical reactions of alkyl halides; thus, you can expect to see such compounds ...
