Nitration of methylbenzoate Aim: The aim of the experiment is to success copiousy perform the nitration of Methylbenzoate by the recrystalisation method and in doing so obtaining a melting top dog and the infra-red spectra graph of the product. Introduction: Methylbenzoate is an aromatic compound and it is structur completelyy associate to Benzene. It has an negatron rich aromatic ring which take a shits it insecure to electrophiles this in turn making them react. A common electrophile is utilize in this reaction, which is the NO2+ nitronium ion. It is produced by reacting nitric acerb and sulfuric acid simultaneously. The unaccompanied pair from oxygen breaks the OH hamper when it comes in foregather with sulphuric acid. Furthermore, NO2OH2 break and dissociate to form H2O wet on with the electrophiles NO2. The electrons from the benzene ring attack NO2 ca apply the mental image bond to break. Multiple resonance is created from the movement of electrons. The hydrogen corpuscle which is released reacts with HSO4 to patch up sulphuric acid H2SO4 which is known to be utilize as a catalyst.
