PRELAB EXERCISE EXPERIMENT 21 Synthesis of Aspirin (Acetylsalicylic Acid) What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. The procedure calls for cautious addition of water to the reaction mixture while it is still hot. What purpose does the addition of water serve and why should the addition be done while the reaction mixture is hot? Provide an equation for the reaction involved.Using the quantities of salicylic acid and acetic anhydride...

Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...

what is my limiting reagent, theoretical yield
calculated from moles , and % yield for the synthesis of banana
oil?
Isoamyl acetate (banana oil) is made by the acid
catalyzed reaction (fischer esterification) between isoamyl alcohol
and acetic acid. sulfuric acid was used as the catalyst for the
fast conversion of product from starting alcohol and acid. the
catalyst only affects the rate of the reaction not the extent of
the reaction.

Laboratory studies of protein synthesis often involve the addition of a radioactively labeled amino acid and natural or synthetic RNAs to cell extracts that provide the ribosomes, translation factors, tRNAs etc necessary for translation. Conversion of the labeled amino acid into protein is measured by precipitation using trichloroacetic acid (only proteins precipitate under these conditions). Conversion of amino acids into an acid-precipitable form is measured as a function of time to estimate the rate of protein formation.In the following experiment,...

1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...
