reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand‚ the five compounds in Bromine test with light reacted positively. In Bromine test dark‚ Hexane and Unknown hydrocarbon 1 did not react because light (UV) is absent. Lastly‚ in Tollen’s reagent‚ only Acetylene reacted positively

C9H9OCH3. Since all these facts have been established about the structure of anisene‚ what is to be determined from this experiment is the structure of the unsaturated side chain and its location. In order to do this‚ anisene will first be oxidized with KMNO4 so as to then identify the oxidation product and establish the positioning of the side chain. The reaction is as follows: Finally purification of the structure of the unknown oxidized component‚ its structure shall be determined by obtaining the

this experiment‚ we are used to prepare benzoic acid from benzene. Potassium permanganate is used this operation as an oxidizing reagent‚ it is used to oxidize the benzoic acid as well as acting as a catalyst for the reaction. Potassium permanganate (KMnO4) is a very strong oxidant which is able to react with many functional groups‚ such as secondary alcohols‚ 1‚2-diols‚ aldehydes‚ alkenes‚ oximes‚ sulfides and thiols. It is heated under a reflux‚ this (heating in a flask with a condenser placed vertically
