Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

Since attracted international market‚ have not explored aware of the pros and cons of foreign markets‚ it has to enter the markets of other countries. I agree with the authors‚ it’s better to think more carefully and use of analytical tools to make accurate judgments and make the most important decision-making. The distance between the two countries can be revealed‚ along four basic dimensions: cultural distance

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

Reaction Paper The article “The Failure of the Euro: The Little Currency That Couldn ’t”‚ by Martin Feldstein‚ is a case about why the Eurozone has failed‚ is failing‚ or at best will fail. To prove his point‚ the author uses explicit examples such as the economic disaster occurring in Greece‚ while at the same time aiding the economic growth in Germany. Feldstein also demonstrates how the Eurozone also has allowed much room for error and has forced the hand of many European countries in one way

done to solve their problems (Sekaran‚ 2003). There are two types of research. Both have many similarities in the scientific process of the research; however the end results differ in their use. Both types of research can be business research. “Business research is described as a systematic and organized effort to investigate a specific problem encountered in the work-setting that needs a solution” (Sekaran‚ p5‚ 2003). The first type of research is formal research. Formal research is often referred
