The following are equivalent ways of asking about the acidity of an H atom: • What is the most acidic H on the molecule? • Which H is associated with the published pKa value? • Which H on the molecule is easiest to remove? • Which H on the molecule takes the least energy to remove? • Which bond to an H is most polarized? • For which H atom is removal least uphill in energy? • Which bond to an H atom, when broken, results in the lowest PE conjugate base? We will often find the last of these questions is easiest to answer. To do this, find all the different Hatoms on the molecule, and draw all possible conjugate bases.Only the lowest-energy one is the “real” conjugate base. Identify this structure, and you have found the most acidic H. Use this strategy to find the most acidic H on each of the following molecules. Note: Each structure hasat least three different kinds of H’s, so draw at least three unique conjugate bases for each.
As we will see in later chapters, many steps in key reaction sequencesinvolve acid–base reactions. (a) Draw curved arrows to illustrate the flow of electrons in steps [1]–[3]. (b) Identify the base and its conjugate acid in step [1]. (c) Identify the acid and its conjugate base in step [3].

Draw the products of the following acid/base reactions, depict the proton exchange with electron-pushing arrows, AND circle the proper reaction arrow to indicate if reactants or products (or neither) are favoured at equilibrium. Using the provided pKa table, write all relevant pKa values (i.e. for the two reactants if available and the conjugate acid). Finally, label the acid, base, conjugate acid, and conjugate base.
