Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which involves mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks

Review Problems#3 Question-1 Mark Goldsmith ’s broker has shown him two bonds. Each has a maturity of 5 years‚ a par value of $1‚000‚ and a yield to maturity of 12%. Bond A has a coupon interest rate of 6% paid annually. Bond B has a coupon interest rate of 14% paid annually. a. Calculate the selling price for each of the bonds. ANSWER: b. Mark has $20‚000 to invest. Judging on the basis of the price of the bonds‚ how many of either one could Mark purchase if he were to choose it over

Include observations such as appearance of the reaction‚ color of product‚ etc. If the experiment was a preparative one‚ you should also report your percent yield: Percent Yield = Actual or experimental yield in grams (or moles) X 100 Theoretical or calculated yield in grams (or moles) Show all of your calculations! Graphs should be done on graph paper. Note: Our lab manual contains a "Data Report Sheet" for each experiment.

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

1) What is FedEx’s “Common Language” of Quality? Is it Important for a company to establish a “Common Language“ of Quality? If so‚ Why? FedEx common language of quality is People –Service-Profit (PSP). It articulates that when people are placed firs‚ service and profit follow. Another would be its QIP program which also articulates that quality must be a part of the way that FedEx does Business‚ not part of the time‚ but all the time. Thus themes such as “Do it right the first time”‚ Make the

Life without a Television When my family’s only television set went to the repair shop the other day‚ my parents‚ my sister‚ and I thought we would have a terrible week. How could we get through the long evenings in such a quiet house? What would it be like without all the shows to keep us company? We soon realized‚ though‚ that living without a television for a while was a stroke of good fortune. It became easy for each of us to enjoy some activities alone‚ to complete some postponed chores

A particular situation that I would do differently than the character (Christopher) is when Christopher decided to travel to London all by himself; with no help or directions. First of all‚ if I was Christopher‚ I would never even think about moving to London all by myself at such a young age. If I was in the story‚ I would absolutely with no doubt ask if he is making the right decisions not only for himself but for his father. If I were in Christopher’s shoes at the exact same situation‚ I would’ve

from heterocyst. To produce hybrid seed‚ elite inbred varieties are crossed with well-documented and consistent phenotypes (such as yield) and the resulting hybrid seed is collected. Another factor that is important in hybrid seed production is the combining ability of the parent plants. Although two elite inbred parent plant varieties may produce the highest yields of their crop‚ it does not necessarily mean that crossing these inbreeds will result in the highest yielding hybrid. The level
