Aldol condensation

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 a melting point analysis and a UV/VIS analysis were used to analyze the composition of the obtained product. Finally, the computer model was examined to learn about the optimal angles and strain within the molecule. The dibenzylketone, 1,3-diphenyl-2-propanone,…

There are several different reactions that can be utilized in order to end with a product that includes the synthesis of carbon-carbon bonds, however for this experiment the reaction that was utilized is aldol condensation. An aldol condensation is when an enolizable aldehyde or ketone undergoes a reaction, in the presence of a base or acid, and gives a beta unsaturated ketone or aldehyde (Utah Valley University, 2009). This type of reaction can also add carbonyls to a compound, using similar…

The aldol reaction is one of the fundamental reactions of organic chemistry, since it leads to the formation of a new carbon–carbon bond and is broadly applicable. Asymmetric synthesis is the reaction that produces one enantiomer in excess of the other. The melting obtained during the lab was 56-59 degree celsius, however literature melting point was not found online. Another group obtained a melting point of 44 degree celsius, which means a difference of ten degree celsius. The professor…

Global warming, terrorism, illiteracy, natural disasters, hunger. These are some of the many problems that the Earth, as a global community, combats frequently. However, one problem stands out. It stands out because, unlike some others, the solution is seemingly so obvious and so simple. It is the problem of hunger and poverty. Indeed, according to World Food Programme (WHP), it is the world’s greatest solvable problem. They point out that “no scientific breakthroughs are needed to solve…

Diels-Alder (DA) reaction is a very well-known reaction in Organic Chemistry. A Diels- Alder reaction is considered to be a [4+2] concerted cycloaddition, where you have a diene and a dienophile that come together to form a type of cyclohexane. The four pi bonds of the diene and the two pi bonds of the dienophile come together to form new sigma bonds which are more stable than the original pi bonds. The reaction is concerted which means it happens in one step, making this a fast reaction.…

Boldly stated within a viral video titled "Wealth Inequality in America" is that "[most people] certainly don 't have to go as far as Socialism to find something that is fair for hardworking Americans," a statement that colorfully highlights one of the largest issues in America today: the wealth gap. Using statistics, the creator of the video proves that the saying “While the rich get richer, the poor get poorer” is true; as the rich are given an excess of opportunities to gain more money, the…

Someone once said, “The rich get richer; there’s no denying that. They get a lot richer. And the poor get – well, what do they get? Too often, they get ignored. Or we don’t even know who they are.” In today’s economy there has been an issue about the unfair distribution of wealth, which is causing a major gap between the rich and poor. Slowly, the Middle and lower classes are disappearing from the economy while, a small part of people are getting richer. The truth is, the gaps between classes…

illegal activity. “ Between 1984 and 1992 the average salary in the informal sector grew by 10%, while in the formal sector the increase was only 3%.”(Rubio 805-816) In a greater sense, the growth of the Colombian economy is powered informal sector. Consequently, the elite, upper class and upper middle class are the main bodies behind this growth. Therefore, the poorer part of the community is left with scarce resources, uneducated and exploited. The greatest challenge, as a result, is security…

The, “American Dream,” is practically the leading cause of crime in the United States. Why do people commit crimes? Often for money and personal gain, but why? Often you will see people who commit crimes just to make ends meet, but more often than not you see people committing an excess of crime, and why do you think they do this? To live the “American Dream” and give their lives a sense of meaning. Wealth is glamorized in today’s culture. When you have role models, athletes, politicians, and…

18.Destitution and Despotism: Those in Squalor and Those Who Squander The words rich and poor are terms used that are on complete opposite sides on the spectrum for how much revenue someone makes and their overall social status. My family has always been fortunate enough to always be in the middle class when it comes to wealth. 21. When I was a little kid I never could figure out what the people with signs sitting by the street were doing. My parents always told me to not give the poor…
