ethers and epoxides can both undergo acid-catalyzed or base-catalyzed substitution reactions. Pimobendan (shown below) is a cardiac drug used to treat dogs with congestive heart failure.
Pimobendan is taken orally, so it has the potential to react with stomach acid (HCl). Using your knowledge of ether reactions, predict if the ether functional group in Pimobendan is likely to react in a dog's stomach. If you think no reaction will occur, explain. If you think a reaction will occur, describe the mechanism and predict the product.

Carboxylic acid esters can undergo acid catalyzed hydrolysis, neutral hydrolysis and base catalyzed hydrolysis. Below is a table with three structurally related carboxylic acid esters and the second order reaction rate constants for the acid-catalyzed mechanism (k_A) and the rate constant for the base-catalyzed mechanism (k_B). The difference between the three compounds is mainly the substitution of hydrogen atoms on R_1 with the more electronegative chlorine atoms. a) Explain why there is only a small change in k_A for the...
