Question

Using the table of alcohol and esters at the end of this experiment, determine and draw the structure of the ester, the alcohol from which it was produced, and the anhydride necessary in each of the instances below:

a. Started with an alcohol of bp 83C and produced an ester of bp 131C

b. An ester whose bp is ~ 80-85C, was produced from an alcohol of bp ~98-100C

c. This ester has a bp that is more than 30C lower than the bp of the alcohol
