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...
a = Proton transfer b = Lewis acid/base c = Radical chain substitution d = Radical chain addition e = Electrophilic addition f = E1 Elimination g = E2 Elimination h = S_N1 Nucleophilic substitution i = S_N2 Nucleophilic substitution j = Electrophilic aromatic substitution Identify the mechanism by which each of the reactions above proceeds from among the mechanisms listed. Use the letters a - j for your answers.

What is the identifying feature of a redox reaction? 3. What is the oxidation number of a. Mn b. Br – c. Cl in ClO3– d. each element in CNO– (all elements double bonded in this order)
Predict what kind of reaction dopamine is most likely to undergo in water: redox, acid-base, precipitation, or metathesis? Explain your reasoning.
9) 9) Why do aldehydes undergo nucleophilic addition reactions, whereas esters undergo nucleophilic acyl substitution reactions? A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. B) Once the nucleophile adds to an aldehyde, neither H- nor R-can be eliminated because they are strongly basic. C) Aldehydes are more sterically hindered than esters. D) The ester carbonyl carbon is sp3 hybridized while the aldehyde carbonyl carbon is sp2 hybridized. E) Once the nucleophile adds to...

Use the letters a . i for your answers.
Why do aldehydes undergo nucleophilic addition reactions while acyl chlorides undergo nucleophilic acyl substitution reactions? Once the nucleophile adds to the aldehyde, the tetrahedral intermediate is too sterically hindered to eliminate one of the attached groups. Because an Sw2 substitution can best take place on the sphybridized carborwyl carbon of the acyl halide. Once the nucleophile adds to the aldehyde, neither H" nor Rºcan function as a leaving group. so a substitution cannot take place. The carbonyl carbon of the...
