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

4-nitroaniline had a percent recovery of 18.67% and naphthalene had a percent recovery of 80%. Naphthalene had a relatively high percent recovery‚ and the loss of product can be explained by error inherent. The low percent recovery of 4-nitroaniline is mainly due to the fact that anhydrous sodium sulfate was accidently added to the flask. Therefore‚ some product was lost as the aqueous solution with the protonated 4-nitroaniline reacted with the drying agent. However‚ more errors to explain the results

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

DATE: March 21‚ 2011 COURSE: BS Chemistry II APPROVED: ___________ PREPARATION OF AZO DYES ABSTRACT In this experiment‚ the azo dyes p-nitrobenzene azoresorcinol and methyl orange were prepared by the azo coupling reaction. The p-nitrobenzene azoresorcinol dye was prepared from p-nitroaniline and resorcinol. The diazonium salt formed was from the reaction of the cold solution of dissolved p-nitroaniline in hydrochloric acid and water with the solution of sodium nitrite. Azo coupling

Educational Preparation juli mar Grand Canyon University NRS 430 12-18-11 Educational Preparation There are 2 common‚ but different‚ pathways to receiving a RN license. You can earn a bachelor’s degree (BSN) or an associate degree‚ (ADN). While there are similarities between the two programs‚ a BSN takes two additional years of college at a university. Both programs teach nursing skills‚ electives ‚science courses‚ and clinicals. But‚ the BSN program is a more in-depth study of nursing
