Nucleophilic Substitution | Synthesis of n-Butyl Bromide and t-Pentyl Chloride | | Jessica | [Pick the date] | Abstract The synthesis of the alkyl halide n-Butyl Bromide from alcohol is the foundation for the experiment. During the isolation of the n-butyl bromide‚ the crude product is washed with sulfuric acid‚ water‚ and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with sodium

THE FRIEDEL-CRAFTS REACTION: ACETYLATION OF FERROCENE Ferrocene was acetylated in acetic anhydride and phosphoric acid. It proceeded via a Friedel-Crafts reaction without the use of organic solvents or strong Lewis acid. Operations and Observations A mixture of ferrocene (1.5 g‚ 0.008 mol)‚ acetic anhydride (5 mL) and phosphoric acid (1 mL 85%) was heated over a steam bath until all the ferrocene dissolved and the mixture darkened from orange to dark red. The mixture was then refluxed with

Is another form of structural configuration better suited to multiproduct‚ multiservice companies? I do not believe so. As stated on our textbook‚ “Organizations exist for a purpose.” Further‚ their design considerations “seek to create organizations that are both efficient and effective” (Baack‚ Minnick‚ & Reilly‚ 2014)With multiproduct‚ multiservice companies there are many more moving parts‚ meaning more room for error. All the moving parts must work together‚ as parts of an engine. A design

The Present Value Formula is P = A(1+r)-n where P is the present value that will amount to A dollars in n years at interest rate r compounded annually. The numbers are plugged into the formula P = A(1+r)-n and the quantity raised to a power and has a negative exponent of –n. It will look like: P = 33395(1 + .10)-12 Next I will add inside the parentheses. P = 33395(1.10)-12 Now by using the rules of exponents the

Abstract – The synthesis of 4-hydroxy-4‚4-diphenylbutn-2-one was a three week multi-step project. The steps involved protecting the ketone of ethyl acetoacetate with a ketal group‚ followed by preparation and reaction with Grignard‚ then purification by extraction and recrystallization. The yield was 78.5%‚ but there are impurities present suggested by 1H-NMR‚ IR‚ and TLC. However‚ the results do indicate the desired hydroxyketone was formed.

An entrepreneur startup or relatively small corporations‚ new government departments‚ medium-sized retail stores‚ and small elementary school districts. The organization consists of the top manager and a few workers in the operative core. There is no techno-structure‚ and the support staff is small; workers perform overlapping tasks. An example of this structure is a local family restaurant called the Pioneer
