how do i find yield of crude product obtained in the reaction? and how do i find theoretical yield in grams and percent yield. let's say my grams after recrystallization is .769 grams . I converted acetanilide to p-bromoacetanilide. I have a recyrstallized p-bromoacteanilide after finsihing the experiement. I want to know this infomration for my 0.769 grams of p-bromoactenalidie that i have after finsihging the xperiment.

Answer #1

You have 0.769 gram of p-bromoactenalidie after experiment.

It is experimental value. Now calculate the mass of p-bromoactenalidie theoretical on page by using reaction. By theoretical value you will be able to know how much p-bromoactenalidie should be formed. I think theoretical value of mass should be greater than experimental value. Now calculate the percent yield by dividing experimental value by the theoretical value.

Percent yield = experimental value * 100 / theoretical value

2. You have carried out a synthesis reaction and isolated the solid crude product. Scrutiny of its 1H NMR spectrum indicates the presence of an impurity, which you estimate to be approximately 6-8% of the total sample. You decide to purify it via recrystallization and know that you will first need to determine which solvent or solvent pair would be suitable. Describe what you would do and how you would evaluate your results. What properties of the solvent would you...

How to calculate limiting reagent and percent yield? 4-methylcyclohexanol --> 4-methylcyclohexene I used 23 mL 4-methylcyclohexanol and 5 mL of Phosphoric acid. Do we use phosphoric acid to calculate theoretical yield if it is a catalyst? If we do then my percent yield comes out to be like 160% which is wrong because I have to use the limiting reagent which would be phosphoric acid. What do I do? 23mL 4-methylcyclohexanol (.914g/1mL) = 21g 21g (1mol/114.2g) = .184 mol .184...

I am struggling to understand how to find what is the reagent used in a reaction. I have these 4 problems and I must figure out what "reagent used in reaction". My classmate described the reagent as the ractant that is entirly consumed when a reaction goes to completion. It determines how much of a product you can make. Cu(s) + 4 HNO3 (aq) –> Cu(NO3)2 (aq) + 2NO2 (g) + 2H20 Cu(NO3)2 (aq) + 2NaOH (aq) –>Cu(OH)2 (s) +...
