In Marie de France’s poem “Bisclavret,” a baron named Bisclavret trusts his wife with personal information that he has always kept to himself: he is a werewolf. After much probing, he also tells her that the only way for him to transform back into a human is by putting his clothing back on, which is why he hides them next to the woods and by the path. Rather than being loyal to her husband, the unnamed and horrified wife goes to another knight who has been trying to court her for years and tells…

The purpose of this experiment was to use aldol condensation methods to synthesize colored cyclopentadienone and then UV/VIS spectrophotometry to characterize the dienone structure synthesized. The information gathered from the UV/VIS analysis was then compared to a computer model of the desired product to analyze the optimal 3D structure of the dienone. The base catalyzed condensation reaction was used to form the product for analysis, followed by vacuum filtration to recover the product. Both…

INTRODUCTION: In this lab, proper laboratory technique was implemented to have the experience in the lab. Furthermore, the unknown solution needed to be investigated, to determine the solution’s macromolecules. Three methods were comprised to determine the unknown but a set of other solution were used to help as indicators to match the unknown solution’s results. It consisted of biuret, iodine and benedict solution. Iodine solution is used to determine if the source had starch or glycogen.…

The boiling point of an organic compound determines its structural features and physical properties of the compound, which helps us to name the characteristics. Boiling point defined as the “temperature at which the vapour pressure of the liquid is the same as the pressure of the atmosphere on the liquid surface”. (Mahaffy, P, Bucat, B, Tasker, R, Kotz, J, Treichel, P, Weaver, G, McMurry, J 2011). The boiling point 1-hexanol, 2-hexanone, 1-pentanol and 3-methyl-1-butanol are represented in the…

The manufacturing of pharmaceutical tablets involves several main steps including blending, granulation, drying and milling. Each step is known as a unit operation and will be outlined below. The ingredients to make a pharmaceutical tablet will include the active pharmaceutical ingredients [API], and may require a bulking or binding agent which allows the tablet to be sufficiently large for consumption and provides sufficient surface properties of the particles within the mixture to facilitate…

The purpose of this lab was to prepare tetraphenylcyclopentadienone most commonly known as tetracyclone. This involved a 3-step synthesis over the course of 3 weeks. The first step was the preparation of benzoin, which was completed through self-condensation of benzaldehyde with thiamine used as the base catalyst of the reaction. The next step was the preparation of benzil from the oxidation reaction of benzoin with nitric acid. In the oxidation reaction, the alcohol functional group of benzoin…

In the Acid-Catalyzed Hydration of norbornene, water and sulfuric acid were added to the C=C double bond to form norborneol. Sulfuric acid acted as a catalyst, where it was not consumed in the reaction and helped to propel the reaction forward, as it was vital in forming hydronium ion and breaking the double bond. Both the products endo-norborneol and exo-norborneol were synthesized; however regioselectivity and stereoselectivity played a role as to which product was more preferred and whether…

studied information about chemical reactions and how a catalyst is used to speed up reactions. We have learned that enzymes (proteins) in eukaryotic cells work as a catalyst to make this possible. Each enzyme in a eukaryotic cells has specific molecules it binds to, as they have a specific frame work. This specific frame work of the enzyme is known as the active site, designed to fit very specific substrates (molecules). This creates the enzyme-substrate complex where the chemical reaction…

• What are the strategic choices available? Biocon India Group is a Bangalore-based organization that began in 1978 with the enzyme business. An enzyme, by the way, is a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. That said, the Biocon India realized that growth is imminent and various strategic choices are available. The first strategic choice available to Managing Director, Kiran Mazumdar-Shaw’s Biocon India is expansion…

1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…
