Synthesis Essay

compounds used for synthesis in this lab were Acetaminophen (C8H9NO2) and p-Phenetidine (C8H11NO). Both of these compounds have similar organic structures, however, Acetaminophen resulted in a more pure form of Phenacetin. Additionally, both of these compounds had to undergo specific chemical reactions, in order to form the same molecular structure as Phenacetin. Finally, these compounds had to be recrystallized in order to produce the most pure form of Phenacetin. During the synthesis of…

Chase Smith Mr. Melancon ENGL 1013 October 12 2015 Explanatory Synthesis: In “Is Google Making Us Stupid?” by Nicholas Carr & “Smarter than You Think: How Technology Is Changing Our Minds for the Better” by Clive Thompson, both authors explore several different topics concerning technology and our minds. One of these topics is our reliance on technology, and if it is going too far. Another, is how it’s affecting our cognition, along with what would change if we used it correctly. Carr believes…

For the first synthesis reaction, camphene was converted to isobornyl acetate. In the fume hood, a sample of 1.36 g of camphene was added to a 25-mL round-bottomed flask along with a stir bar. To dissolve the camphene, 3.0 mL of glacial acetic acid was added into the flask. The flask was fastened onto a ring stand and immersed in a water bath that was on top of a stir plate. A thermometer wire was placed in the water bath to monitor the temperature throughout the experiment. After the camphene…

Vitamins are the organic compounds required to carry out a living body’s metabolism and their absence can clump several metabolic reactions in the body. These essential nutrients cannot be synthesized in the body therefore must be taken from an outside food source i.e. plants, fruits, vegetables or animals. Basically there are two types of vitamins in nature; some are water soluble and others are the fat soluble ones. Water soluble vitamins are those which are soluble only in water and are B…

Since suitable crystals for X-ray single crystal analysis was not obtained, to have reliable structural information, HR-TEM analysis of the product was carried out. The average size of the assembly calculated from HR-TEM measurement is found to be 2.8 nm which is in good agreement with the size of the previously reported Pd6L8 assembly where L is the non N-methylated (2.5nm, Fig. 2).9 As first step, to explore the catalytic activity of 1 in copper and phosphine free Sonogashira coupling reaction…

Synthesis ofp-[1-(p-Hydroxyphenyl)-1-(p-Methoxyphenyl)Ethyl]Phenol (HMEP) 0.2 mol of phenol was mixed with the solution containing 100 mL of acetic acid in 200 mL of concentrated hydrochloric acid in 500 mL five necked round bottom flask fitted with anoil bath, thermometer, mechanical stirrer, reflux condenser. The contents of the flask was stirred for a period of 15 min, the solution was heated to 65oC, 0.1 mol ofp-methoxyacetophenone was introduced into a dropwise to the solution for about 6 h…

photosynthesis is composed of two phases: light-dependent reactions and the Calvin cycle. The first stage (light-dependent reactions) occurs in the thylakoid membrane, which absorbs light energy to create NADPH and a proton gradient used to power the synthesis of ATP. The latter occurs in the stroma, and results in carbon dioxide fixation. In this experiment, only the light-dependent reactions were studied. 2,6-dichlorophenol-indophenol (DCPIP) was used as an artificial electron acceptor…

A. RNA doesn’t have thymine. RNA uses Uracil. RNA can leave the nucleus. B. mRNA- mRNA is called the messenger DNA. This RNA can leave the nucleus and delivers information to other parts of the cell. tRNA- Transfers amino acids to proteins. Ribosomal RNA- Forms parts of ribosomal subunits C. Proteins must be synthesised constantly in order to use the codes from genes over and over again. 2. A. During transcription, the enzyme RNA polymerase binds to DNA and separates the DNA strands. It then…

Crucible synthesis essay During times when fear and stress are present in our lives or we are don’t want to suffer the consequences of a situation we tend to use scapegoating as a method to get out of or avoid the situation. As humans, we seem to always be subconsciously looking for things to scapegoat weather it is for our benefit, their own problems and/or society’s problems as seen in the crucible during the Salem Witch Trials. During the time of the Salem witch trials a scapegoat was used…

Assess the impact of evolutionary thought on psychology. Illustrate your answer with examples of relevant research. The notion of evolution, as described by both Lamarck and Darwin in the 1800’s, had such an impact on intellectual life that it has changed the way we study the human mind today. Darwin’s (1859) theory is still widely accepted as what we know as the theory of natural selection, and provides a structure for examining human behaviour. He saw the future of psychology as “based on a…
