What happens if the base (NaOH) is added after the alkyl halide (solution made with 3-chloro-1,2-propanediol...
Williamson Ether Synthesis of Guaifenesin Starting Materials - 2-methoxyphenol (guaiacol): 550 uL - 3-chloro-1,2-propanediol: 500 uL - Sodium hydroxide: 1 mL of 6M Product - Guaifenesin What is the yield expected in (g) and (mmoles)?
for the reaction: acetaminophen + (NaOH/EtOH note: etoh is ethanol) and butyl iodide ---------------> 4-butoxyacetanilide a) The first step in this reaction is to reflux acetaminophen in a NaOH/EtOH solution, followed by the addition of butyl iodide. What is the purpose of using the NaOH/EtOH solution? Would the SN2 reaction still occur if the first step was not completed? Why or why not? b) Upon completion of the reaction (before filtration), an additional 4.0 mL of 1.0 M NaOH/EtOH was...
Why does Ph3CO-MgBr+ dissolve when HCl is added? Write a chemical equation to describe what happens. Does it dissolve in the water layer or the ether layer? Is the final product, tripehnylmethanol, soluble in ether or water? Explain your answer. Please Please answer everything what question is asking and explain answers thoroughly. Thank you.
Need help, numbers 3-6 please show work. and fill out table of chemicals for all chemical used. calculate mmol in the table as well show work please and each of these must be listed in its own row. There are 10 column headings: IUPAC name OR common name, structure, CAS number (Chemical Abstract Service number) molecular mass, melting point (if applicable), boiling point (if applicable), solubility (in water, if applicable), density, amounts to be used in the experiment, and the...
3. Calculate in the titrant. 4. Another 1,00 mL of the NaOH solution is added after the equivalence point. Calculate e reaction mixture. in the 5. Suppose 10.00 mL of water was added to the HCl solution before the titration was begun. How would your answers to questions 1-3 change? EXPERIMENT 10 Name QUANTITATIVE ANALYIS III STANDARDIZATION OF A STRONG BASE SOLUTION PRE-LAB EXERCISES Titration of 5.00 mL of a solution labeled 0.237 6 M HCl requires addition of 40.02...
Extraction Q1. Why doesn’t the neutral organic compound dissolve in the 1.5 M NaOH solution? Q2. Why is diethyl ether a good choice for the organic solvent in this extraction experiment? Q3. What experimental difficulty would you encounter if you neglected to include the drying step before evaporating the ether solution of the neutral organic compound? Q4. Why are the two organic compounds recrystallized before their melting points are determined? Q5. What IR bands are most useful in distinguishing a...
Organic chemistry post-lab question: "Why is important to add the alkyl halide dropwise in your reaction? (Hint: your reaction is not heated, but you still need a water-cooled condenser!)" Please answer in detail! Here is a copy of the experiment, thank you! The Grignard reaction is an important synthetic process by which a carbon-carbon bond is formed. Magnesium metal is first reacted with an organic halide. The resultant organo-magnesium halide (Grignard reagent) is then combined with a carbonyl compound, ultimately...
question 2 and 6 thabk you Exercises 1. (a) Calculate the volume of 6 M NaOH required to react completely with the amount of methyl salicylate you used. How much of the 6 M NaOH that you used was in excess of the theoretical amount? (b) What volume of 3 M H SO is needed to neutralize all of the disodium salicylate and the excess NaOH present after the initial reaction? How much sulfuric acid was in excess? 2. Refer...
1.) 4.00 g of NaOH are dissolved in water to make 5.00 L of solution. What is the concentration of hydronium ions, [H3O+], in this solution? Express your answer with the appropriate units. 2.) If you wanted to determine how much KOH (potassium hydroxide; a strong base) was dissolved in water, you could titrate it with a known amount of KHP (potassium hydrogen phthalate; a weak acid) until a color change indicates that the base is completely neutralized. The molecular...
