1-An unknown sample does not react with Jones' reagent, does not react with Benedict's reagent, forms a precipitate when dinitrophenylhydrazine is added to it, but does not form a yellow precipitate after performing the iodoform test. The unknown is Select one:

a. Benzaldehyde

b. Ethanol

c. 3-pentanone

d. Acetone

e. Hexanal

f. Glucose

2- An unknown is either glucose or hexane. Which of these tests could you use to decide ?

a. Jones' test

b. Benedict's test

c. DNP test

d. Iodoform test

3- Which of these compounds will yield a positive test with the Jones' reagent?

Select one:

a. 3-Butanone

b. Benzaldehyde

c. 2,4-dimethylpentane

d. 2,2-dimethylpropanol

e. Benzene

4- what two impurities are most likely to be present in the asprone that you prepared? Use the results of the FeCI3 test any observed odor to help answer the question?

5- If your % yield is less than 100%, what may account for this ? Be as specific as possible. If your % yield is over 100%, what may account for this? Be as specific as possible
