    functional group would be present in solution? Potassium Magante is K2MnO4 whereas the permanganate is KMnO4‚ in the second one the Mn as a higher oxidation state of +7‚ the other one just +6. It would show that a double bond is present. (It oxides the alkene to a diol‚ which changes the oxidation state of the Mn changing it’s colour) Original post by GyasiW) First of all I would like to know the differences in formulae between Potassium Mangante and Potassium Permanganate. Secondly‚ In a test between

    Dehydration refers to a chemical reaction where the reactant loses a water molecule. In the presence of a strong acid like 85% phosphoric acid‚ an alcohol like-2-methylcyclohexanol can be dehydrated to form an alkene. In this experiment‚ alcohol was dehydrated by E1 elimination‚ in order to synthesize cyclohexene. First‚ alcohol is protonated by the acid. Second‚ during E1 elimination‚ a carbocation is formed by the removal of an oxonium ion to yield a secondary and a tertiary carbocation. The receiving

In one line of inquiry it has been observed that a mixture of 2-methylcyclohexanol diastereomers gives rise to a mixture of three isomeric alkenes Todd(1994)JCE:71‚p440; Feigenbaum(1987) JCE:64‚ p273; Cawley (1997) JCE:74l‚ p102. Explaining the presence of the three alkene products requires an intense synthesis of information communicated in a typical SOC textbook. The continued popularity of this experiment is corroborated by the observation that Googling

    Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is an alkene. Procedure: The procedure

    The reason it is able to react with the Maleate alkene is due to the presence of the ester groups. these groups are allowing the maleate to resonate and pull the electrons from the alkene towards the esters creating partial positive charges on the carbons of the carbon-carbon double bonds formed next to the carbon-oxygen bonds. Pbu3 can attack these partial positive
