- What is the equation for the expected reaction between dimethylformamide (DMF) and sodium iodide? What are possible reaction products? (Please include structures in explanation) If you were to change the concentration of the solvent (DMF) how would that affect the reaction (would more product or less product be produced)? (Please make sure to make answers easy to follow)I want the sequence of the reaction to get to the target for number 3 thank uMost imine formation reactions are performed in the presence of molecular sieves ormagnesium sulfate. What is the purpose of these added reagents?
- Why is it important to thoroughly vortex the contents of the vial after adding reagent 4 (Steps 3 and 4., stage 1). To ensure that the two immiscible solvents come into contact with each other, permitting the derivatization reactions to occur. B.To ensure that the solution is mixed thoroughly. To ensure that all the amino acids are transferred to the lower aqueous layer so that a full extraction occurs. To remove all the interferring compounds by transferring them to the upper organic layer Hint: Reagent 4 is the derivatizing agent dissolved in octane.Please show mechanims and explain the procedure for the following image.Given the information pictured, The final step of the reaction sequence uses PhLi. Provide a reason and possible mechanism by which this final elimination and hydrolysis reaction would occur.
- On the axes below, sketch the graphs which show the result of adding: 0.1M NaOH to 25cm3 of 0.1M ethanoic acid. 0.1M NaOH to 25cm3 of 0.1M H2SO42) Another method for the above reaction starts with 4-aminophenol hydrochloride (the conjugate acid of 4-aminophenol). The treatment of this the hydrochloride salt with sodium ethanoate (acetate) buffer produces 4-aminophenol which is then able to react with ethanoic anhydride as per our method. i. Why is 4-aminophenol hydrochloride not suitable for direct reaction with ethanoic anhydride? ii. Draw a mechanism (i.e. curly arrows) showing the deprotonation of 4-aminophenol hydrochloride by sodium ethanoate to form 4-aminophenol (the free base).based on this video: on Hinsberg Test Tests for Amines - MeitY OLabs (8.5min) https://www.youtube.com/watch?v=j5jgMUWri8U Write the reaction (two-step, in skeletal) of each test amine when tested in the Hinsberg Test.
- Describe how the product is purified. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The…Experimental observations show that thiocyanate (SCN- ), the conjugate base of thiocyanic acid (pKa = 1.1 at 25 °C), is quite soluble in neutral water at pH > 2. In the space provided below, explain this experimental observation. That is, why does SCN– readily dissolve in water when the pH > 2?At the start of lab, Anthony adds vanillin to his Erlenmeyer flask, then adds sodium hydroxide, and lets the suspension cool. i. With minimal words, identify the reaction that takes place between sodium hydroxide and vanillin. ii. Is sodium borohydride capable of inducing the same reaction as (i)? Explain.
