treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to reduce pain and fever. In this experiment it is prepared by the reaction of p-aminophenol with acetic anhydride‚ as illustrated below. Results: Isolation

sulphuric acid will act as electrophile. C5H10 + H2SO4 ==> C5H11.HSO4 For the aromatic hydrocarbon‚toluene doesn’t react with bromine water. This is because Br2 is electrophilic enough to attack double and triple bonds‚ but not electrophilic enough to attack the pi bond system of the benzene ring of toluene.For the reaction of between toluene and aqueous potassium manganate the reaction will change the toluene to benzanoic acid and the color of potassium manganate change from purple to slight purple Objective

The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g + 31.9988g = 147.01456g or 147.0 g CaCl2 1g CaCl2 * 2H2O x (1 mol CaCl2 *2H2O/147g CaCl2 *2H2O) = 0.0068 mol of CaCl2*2H2O Molar mass was then

Name: University: Course: Tutor: Date Criminology is a term that refers to any kind of study associated with crime and criminal justice. Feminist criminology in the late 1960 into the early 1970 was largely concerned with the victimization of women. The emergence of Feminism that sort the elimination of all forms of gender inequality in women lead to contemporary feminist criminologists‚ whose contributions have led to the modern understanding of women as victims‚ offenders and
