hydrogen substitution. However‚ this is not thermodynamically favoured because a sp3 hybridized carbon is generated‚ which disrupts the cyclic conjugation. In order to regenerate the aromatic ring‚ a proton is lost at the sp3 hybridized carbon. Thus‚ p-Nitroaniline can be prepared by means of electrophilic aromatic substitution. To begin‚ nitric acid needs to be activated as it has little electrophilic power. Thus‚ concentrated sulfuric acid is added to protonate the nitric acid. Dehydration produces the

Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ molecules of other compounds
