Preparation of 1,3-dinitrobenzene
Benzene itself cannot be used in school laboratories due to its carcinogenic nature. This practical illustrates an electrophilic substitution reaction by converting nitrobenzene into 1,3-dinitrobenzene using the NO2+ ion as the electrophile. The purity of the product you make is then tested by thin layer chromatography and measuring its melting point. The theory behind this practical is really only for Higher Level...
