Fmoc-Cl is a derivatizing agent (used to alter an analyte). It reacts with glyphosate to form another new compound which absorbs light more strongly than the initial glyphosate compound.
Option B is correct.
Fmoc-Cl is soluble in Dichloromethane while the glyphosate/Fmoc-Cl is water soluble. So dichloromethane is added to separate out Fmoc-Cl from the new compound.
Option A is correct.
In the lab procedure, it is necessary to add a reagent to glyphosate called fluorenyl orthochloroformate,...
Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.
HNMR
Discuss the percentage yield of the reaction. Explain and provide...
i need help with this lab please. can i get someone to answer
the entire thing. thank you
Instructor Equilibria of Coordination Compounds OBSERVATIONS AND DATA 1. The formation of complex ions with ammonia The net ionic equation for the reaction of excess Cuso, with NH, is 24 Cu2+ + 4NH3 [cu (NH3)4] The predicted effect on the reaction above of adding excess NH, (based on Le Châtelier's principle) is The reaction will shift to the night and product formation...
Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
The following questions are from an experiment titled
Friedel-Crafts Alkylation for Organic Chemistry II Lab. There are
pictures attached of the lab manual.
2) Is this method a good route for the preparation of
p-sec-butyltoulene? Give reasons for your answer.
3) Why do you use a large excess of toulene. What are its
functions?
4) What is the purpose for adding the hydrochloric acid to the
water in the separatory funnel in step 5? Hint: If no acid is
added,...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
Attached is the lab experiment. Here are the questions I need
help with:
1. What is the purpose of each of the following steps in this
experiment?
a. Adding solid NaCl to the reaction mixture
b. Repeated washings with water, sat'd NAHCO3, and brine
c. the pipet column chromatography
2. Which compound, cyclohexanol or cyclohexanone will have a
higher Rf on a TLC plate?
3. What is the advantage of using sodium hypochlorite as an
oxidant over CrO3 or Na2Cr2O7...
please answer all these questions, thank you.
CHEM 242L Exp. 4 Report/ Synthesis of Oil of Wintergreen Name Score: 20 1) Assess the effectiveness of the experiment and your technique by A) reporting the yield of each step in grams and percent as well as the overall percent yield (What is "overall percent yield?). SHOW ALL CALCULATIONS! B) Give a complete analysis of the identity and purity of your final product and any isolated intermediates 2 What was the purpose...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
1 - Provide a balanced equation for this reaction
2 - Provide a mechanism for the transformation of cyclohexanol
into cyclohexanone
3 - Provide a flow chart for the workup procedure for isolating
cyclohexane from all the by-products, making sure to note in which
layer you expect to find your product in each extraction.
4 - Provide the theoretical yield of cyclohexane in this
experiment.
