Essay about Synthesis of Benzilic Acid - 1107 Words

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day amp; Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5% and 21.9% respectively. The calculated melting point of benzil was 90.1-91.6 which suggested some impurities, but the MP of benzilic acid was 149.3-151.5 which suggested a pure yield. The IR further confirmed the identity of benzylic acid with two†¦show more content†¦The solution was then allowed to crystallize and the solid benzilic acid was dried, weighed, and used to obtain melting point and IR spectra.

In addition, this converted alpha diketone was then subjected to rearrangement to a carboxylate salt, then acidification, to produce an alpha-hydroxyacid. In this experiment, benzoin was used and converted into benzil, which was then used to synthesize benzillic acid.

Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained, as well as a melting point rangeRead MoreMultistep Lab1416 Words   |  6 Pagesto Produce Benzilic Acid Abstract The objective of the lab was to produce benzilic acid from benzoin. Benzoin was successfully oxidized with nitric acid to form benzil. The percent yield of benzil was 59.26% and the melting point range was 94.1-95.5 °C. The literature melting point of pure benzil is 95 °C, which indicates the correct product was obtained. Benzil was then rearranged using potassium hydroxide to form benzilic acid.

Free Will And Determinism Can Go Together - 1447 Words

Free will is one of the great debates among humans. What is it and do we even have it are two common questions. Freedom is not always easy to define but there is one compelling version of free will. I believe that humans are not truly free, they have free will but much of their lives are determined by other external causes because of the dual nature of decisions. First I will argue what the theory of compatibilist is and why it is the most reasonable. Then I will look at the moral responsibility someone has with this view and its opposing argument. To be a soft determinist or a compatibilist, there are certain conditions that must be followed. One is the belief in the free will, another is the belief in determinism-or that actions and thoughts have causes, and the final is that both free will and determinism can go together. (Hume 113-114). This view still allows for people to be morally responsible for their actions while suggesting that it is possible that there where underl ying means to the thought of that action. This theory on free will is believable because it allows for both internal and external factors to influence decisions. This shows that all choices have both a mental component and a physical component. The internal or mental component is how a person believes that he can directly influence or change a situation. The physical or external component is how the outside environment or previous decisions create the choice that a person has to make.Show MoreRelatedDeterminism In Oedipus1163 Words   |  5 Pagesnot knowing their real relationship. Thus, he fulfilled the prophecy. Although the story of Oedipus is an extreme example, the book, Introducing Philosophy says, â€Å"The story of Oedipus†¦is perhaps the most stirring picture of Greek determinism† (Solomon 431).

This is because everyone wants to know if the decisions they make are truly theirs or if their decisions matter at all. If everything is predetermined then what you choose wouldn’t matter because it would be bound to happen regardless of if you chose it or not.

In order to defend the position that free will means that human beings can cause some of what they do on their own; in other words, what they do is not explainable solely by references to factors that have influenced them. My thesis then, is that human beings are able to cause their own actions and they are therefore responsible for what they do. In a basic sense we are all original actors capable of making moves in the world.

Information Free Essays

The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data, which is the plural of datum are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. We will write a custom essay sample on Information or any similar topic only for you Order Now Raw data refers to a collection of numbers, characters, images or other outputs from devices that collect information to convert physical quantities into symbols that are unprocessed. The data being collected by Freeway Ford pertaining to the dates when cars were purchased and the names of the owners are just numbers and characters, and as my definition of Information below will show, the inability of Freeway Ford to translate this data into anything meaningful renders it short of being described as information. Information, on the other hand, is raw data that (1) has been verified to be accurate and timely, (2) is specific and organized for a purpose, (3) is presented within a context that gives it meaning and relevance, and which (4) leads to increase in understanding and decrease in uncertainty. The value of information lies solely in its ability to affect a behavior, decision, or outcome. A piece of information is considered valueless if, after receiving it, things remain unchanged. In the case of Freeway Ford, if the company had been contacting customers about routine maintenance with the data it had collected about the purchase dates of cars and the names of their owners, and if the company had further followed up three to four years later, when car owners are generally known to be ready to trade in their cars to try and get them to do trade-ins with Freeway Ford, the data they had collected would have translated into something useful, something that could change the way business was being done, and would have information.
