This page gives you the facts and a simple, uncluttered mechanism for the electrophilic substitution reaction between benzene and sulphuric acid (or sulphur trioxide). Heat benzene under reflux with concentrated sulphuric acid for several hours. The electrophile is actually sulphur
A commonly quoted example of the use of colorimetry in rates of reaction is the reaction between propanone and iodine in the presence of an acid catalyst. The solution of iodine in propanone starts off brown, and then fades through orange to yellow to colourless as the iodine is used up.
Some background on benzene (including links to more detailed discussions) and a general mechanism which covers several of benzene’s reactions.
23 Nov 2016 The structure of pyridine e considerably resembles that of benzene. Within the Landolt iodine clock reaction Potassium Iodate and Sodium are lost) and reduction (where electrons are gained) (Chemguide, 2013). When
