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

In the book anthem‚ I agree with the quote “To be free ‚ a man must be free of all his brothers” . All men have a mind of their own. They all have different emotions and opinions. Equality has taught him that him and his brothers are one. In his society he is expected to be with his brothers and try to be more superior. His brothers teach him that if they weren’t alive he wouldn’t be either. The quote‚ “We strive to be like all our brother men‚ for all men must be alike.”(Chapter 1 paragraph 7)‚

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

I chose to observe my race and ethics class in new castle. The class had an Italian teacher from philly with a very strong personality. Only three males that happened to be black both older but come from three different walks of life. The first is a 34 year old from New York military background

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

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane.

situation going on in today’s society on protesting the national anthem. Protesters believe that not standing for the national anthem is not being disrespectful. Others believe they are being disrespectful and therefore they are wrong. Protesting the national anthem is not disrespectful because of inequality of race‚ simple rights‚ and citizen freedom. Many protesters are not disrespecting the flag or the national anthem; they are simply protesting for equality between both races.
