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

Evaluate how the name of a muscle can distinguish its location‚ action‚ shape‚ and function. Select five different muscles to make this distinction. Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone‚ but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions‚ like the genioglossus

Synthesis Paper Focus Question: What role do the Harry Potter books play in children’s education? In my freshman year in high school‚ Mr. Mehta‚ the Head of the English department‚ made some changes to our school’s English curriculum. One of these changes included introducing the fifth book of the Harry Potter series‚ Harry Potter and the Order of Phoenix‚ to our reading list. Mr. Mehta’s simple action attracted more attention than ever before! While students lauded his decision‚ most parents

1680-1750cm-1 that represents a ketone functional group is present‚ and a broad sharp peak ranging from 3200-3559cm-1 which is indicative of concentrated alcohols and phenols. This is‚ however‚ not supported by the NMR spectra‚ and hence suggests the presence of impurities‚ especially in regards to the concentrated alcohol and phenol peak. The boiling point of butyl acetate is 126C according to literature. However‚ the boiling point observed during distillation was 117C‚ a lower measurement likely

tert-butyl chloride. The crude product was distilled to yield a pure tert-butyl chloride. The tert-butyl alcohol‚ together with HCl‚ underwent an SN1 nucleophilic substitution reaction‚ which is composed of three steps—(1) propanation of alcoholic oxygen‚ (2) formation of carbocation‚ and (3) attacking of the nucleophile to the carbocation. The experiment was only able to yield 0.504 grams or 5.21% of the theoretical yield of 9.679 grams‚ which is considered as extremely low percent yield. This result could

vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the unknown was measured and recorded. 2 mL of dichloromethane was added to the test tube and then stirred for two minutes. The test tube was then centrifuged for 30 seconds making sure that another test tube equal in volume was placed across from it. A micro pipet removed the liquid above
