If you ran the reaction for this experiment and began with 65.0 mmol of isopentyl alcohol, how many grams of isopentyl acetate could you theoretically produce assuming only a 67.0% attainable yield?

If the yield from the reaction of acetic acid with isopentyl alcohol is 45%, how many grams of isopentyl acetate are formed from 3.58 g of acetic acid and 4.70 g of isopentyl alcohol? The reaction is: CH3CO2H+C5H12O→C7H14O2+H2O Express your answer using two significant figures.
In this experiment, we did a Fischer Esterification using excess acetic acid, isopentyl alcohol, and sulfuric acid to form isopentyl acetate. Then sodium bicarbonate and NaCl were used in the extraction step of the experiment. Is there another method we could have used to calculate percent yield other than using the amount of isopentyl acetate? What are the advantages and disadvantages? (Using GC is not the answer we are looking for.)
Assume you are doing an experiment on the esterification of isopentyl acetate using 1mL of isopentyl alcohol and 1.5mL of acetic acid. Assuming complete reaction, calculate the amount of acetic acid left in the post-reaction mixture at the end of reflux Calculate the amount of 5% aq sodium bicarbonate needed to neutralize the unreacted acetic acid
In today’s experiment, we will react isopentyl alcohol with acetic acid to produce isopentyl acetate. Isopentyl acetate smells like bananas: CH3 O CH3 O + H3COH H3C -H2O H3C O CH3 Isopentyl Acetate However, instead of using conventional heating, we will use microwave energy to promote the reaction and we will use an acidic resin, Dowex-50, in place of the mineral acid to catalyze the process. Questions 1. The three standards have different retention times on the Mini-GC. What physical...
This experiment involved the use of Fischer Esterification to create isopentyl acetate from reacting isopentyl alcohol with acetic acid and sufluric acid. 1. Provide a balanced equation to explain the evolution of gas during the sodium bicarbonate washing step. 2. The microscale synthesis of esters often uses a Dean-Stark trap. A Dean-Stark trap separates and collects water during a reaction. How would using a Dean-Stark trap during a Fisher-Esterification affect the synthesis? 3. Esters are often used in artificial flavorings....
Could anyone please assign the peaks for the 1HNMR of
isopentyl acetate, and explain how you can use this
1HNMR spectrum to characterize the product of a reaction
between acetic acid and isopentyl alcohol? Thank you so much for
the help!

Calculate the percent yield of your product assuming you started with 0.545 grams of Al metal and collect 5.25 grams of alum product? 1) Calculate the number of moles of Al used in your reaction. 2) Calculate the molar mass of alum, potassium aluminum sulfate dodecahydrate (do not forget to include the associated water in you molar mass calculation). 3) This experiment has been set up such that Al is the limiting reagent,(determines the maximum amount of product that could...
We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...
Acetic Anhydride NaOH OCHa OCH3 он In the last experiment, we used 2.0 mmol of vanillin (MW 152.15 g/mol) to produce vanillin acetate (MW 194.18 g/mol). If you needed to scale the experiment up and start with 0.75 moles of vanillin, how much should you measure out in grams? Answer
If the percent yield for the following reaction is 65.0%, how many grams of KClO3 are needed to produce 42.0 g of O2? 2 KClO3(s) → 2 KCl(s) + 3 O2(g)
