Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Synthesis of Methyl Salicylate from Aspirin Esters are a class of organic compounds. An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group. For example‚ the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3). Similarly‚ ethyl acetate (CH3CO-OCH2CH3) is made up of acetic acid (CH3CO-OH) in which the hydroxy group

Wendy Lee’s Peeling Bananas It is not often that I have to read an article or essay several times before I can make an appropriate response. As I read Wendy Lee’s article‚ Peeling Bananas‚ I found myself side-tracked by my own thoughts and feelings of being an African American here in the United States. As I read and reread‚ there were several areas that seemed to jump out at me and make me want to respond - what was so important about being referred to like peeling a banana‚ what in my own upbringing

Experiment 13: Synthesis of 1-Bromobutane An SN2 Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane.
