Born In December on the 27 of 1822 / Died On September on the 28th of 1895. His Childhood - He Was A Very Creative Young Man And Love To Paint And Do Art. He Also Was Very Average School Student Not Very Impressive,but he was very hard working. He loved to fish and draw aka he loved various skills and arts,his father didn’t wanted him to become a Artist. Diseases in 1822-1895 Were Very Prevalent And Cause Lots Of Deaths A Few Of The Biggest Killers Were…
I want to be a part of the NSF-REU program because I know I would make a great contribution. In an informal research project for my biology lab course, I led a team of four in a time-crunched, self-created lab. I took up the role of leadership, assigned tasks, organized meetings and worked outside of class hours to complete the testing. Taking charge wasn’t always easy for me but, at the College of Saint Benedict, there is a NSF S-STEM scholarship program called FoCuS. The program provides…
CHEM 8 A Stereochemistry Report Scaffold Introduction The purpose of this experiment was to find out the absolute configuration of 1-phenylethanol. This was accomplished by using the method of competitive enantioselective conversion (CEC), where 1-phenylethanol reacts with one enantiomer of the chiral catalyst homobenzotetramisole (HBTM). The technique that was applied was thin-layer chromatography (TLC), which will determine the HBTM enantiomer that will react faster. Theory The difference…
Direct Polycondensation The direct polycondensation has 3 main steps: 1. Removal of water. 2. Polycondensation of oligomer. 3. Melt condensation that makes PLA with high molecular weight. Direct polycondensation of lactic acid is the modest reaction that forms lactide simultaneously by the decomposition processes and it is not used for the large production of PLA [19-22]. Back in the days, the direct polycondensation was assumed as the reaction that produces inadequate polymers with low…
Statement of Objectives Whenever my teachers and friends asked me about my aim in life while I was still at school, I used to say merely that I want to be a successful person in society. At that time I was not aware of the exact pursuit and inclination of my mind, nor did I know what it meant to be a successful person! But now, I know the meaning of a successful person; a successful person is one who is well-known to society and his/ her contribution is vital for society and nation. Today I…
Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…
PHYSICAL PROPERTIES: It has two isomeric forms 1, 2, 3-triazole and 1,2,4-triazol with common molecular formula C2H3N3,and both have 69.06 molecular weight. [2]] 1, 2, 4-triazole derivatives simply exist in solid forms. 3, 4, 5-substituted 1, 2, 4-triazole derivatives melts on thermolysis when heated at high temperature3160C for half an hour. 1, 2, 4-Triazole derivatives are easily soluble in polar solvents and slightly soluble in non-polar solvents. However the solubility in non-polar solvents…
Spectroscopic data as reported. Conversion of E-isomer to Z-isomers take place by the process of photoisomerisation, chemical shift and differences between E-and Z-isomers in proton NMR spectral data was useful parameters for ascertaining to stereochemistry. All this synthesized molecules showed antioxidant activity using superoxide (NBT) and DPPH free radical scavenging method. The synthesized derivative compound 7-hydroxy-3-[(3,4,5-trihydrophenyl)methylene]chroman-4-one showed maximum activity…
According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…
Lomotil is a prescription drug that is often used to treat acute diarrhea. It is a combination of two different drugs: Diphenoxylate and Atropine. Diphenoxylate works by disrupting the flow of the intestinal bowels, thus preventing and eliminating frequent bowel movements. However, since Diphenoxylate has narcotic properties, taking it in large doses can lead to a sense of euphoria. This can cause the drug to be misused and abused, or sold as an illicit street dug. In order to prevent this issue…
