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. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

am writing to express my grave concern over discrimination against minority groups in our society. Hong Kong is a multicultural and religiously diverse territory. By the way‚ there is still some conflicts exist between different religion. The minority always have an unfair treatment. Domestic helper is an example of it‚ the salary of them is much lower than the legitimate minimum wage set up in few days ago. Besides‚ the minority children always become the target who were laughed at and bullied

of them don’t know is that they might be treated differently through their race‚ ethnicity‚ or class. One of the biggest aspects that affect this is that there is very little access to health care. The group of people that suffer in the US is the minorities. Most of them do not have the finances to afford medical insurance. Right now‚ medical insurance is being forced into every household in the country. Even the average American is having a hard time adjusting to these changes. An individual could

The model minority myth “holds that Asian Americans have been more successful in the United States than other native ethnic groups and that they have been more successful because of their cultural heritage‚ not the material resources they have brought with them” (Wodziak).

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration
