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

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

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

Reaction Paper Elizabeth Bishop’s “The Hanging of the Mouse”‚ places animals in the roles of humans in reference to an execution. The writer uses animals to replace humans to possibly convey a message or point of view towards the death penalty. In the story‚ the mouse is being executed for what we believe is some sort of crime. It isn’t clear whether or not the mouse actually committed a crime‚ but we are led to believe that an act occurred in which caused the mouse to be executed on this
