AP LANGUAGE SYNTHESIS ASSIGNMENT: ARGUMENTATION SYNTHESIS ESSAY PROMPT Since the beginning of the Industrial Revolution labor battles have been a reoccurring issue across the world. In the mid 1800’s to early 1900s the labor battle heated up in America’s cities as workers fought for their rights and corporations fought to keep wages low. To combat the powerful companies‚ workers united together creating the first labor unions. Since their creation‚ the unions have grown in members as they fight

The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

Abstract This experiment is about the synthesis of 3-nitrobenzaldehyde through nitration. The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low

2013) Protease inhibitors can be used in medicine to treat different diseases and viruses which depend on protease for its mechanism of action. Protease inhibitors are most commonly used in the treatment of HIV/AIDS. Protease is responsible for the synthesis of new viral cells which would cause HIV to spread to uninfected cells. When the protease is introduced however‚ non-infectious vial particles are produced. The protease involved in HIV is called the HIV protease which is an aspartic protease (San
