Acetylsalicylic acid has both anti-inflammatory and antipyretic effects. 1.6: Functional Groups - Chemistry LibreTexts Since we are in a basic environment we don't have any extra hydrogens, so we can't hydrogenate both products. Between ester and carboxylic acid functional groups the highest priority functional group is carboxylic acid. First, the carbonyl, or the carbon double bonded to the oxygen, is made into a really strong electrophile, or electron deficient atom, by adding a hydrogen to the oxygen: Now that the carbonyl is a good electrophile, the electrons from the oxygen on water can attack: Then a proton transfer occurs in order to make the alcohol with R1 a good leaving group: The electrons from the oxygen are pushed back onto the carbonyl, which pushes off the alcohol attached to R1, since that is now a good leaving group: So at this point, we have our first product, salicylic acid. Explore the structure, molecular weight, and the three functional groups of aspirin. represent an ether, however, we have this carbonyl here. As the name implies, carboxylic acids are acidic, meaning that they are readily deprotonated to form the conjugate base form, called a carboxylate (much more about carboxylic acids in the acid-base chapter!).
