- (b) Identify the most acidic H on each molecule, then list its approximate pka in the box provided. H2N Но Но H3Narrow_forwardIdentify the most and the least acidic compound in each of the following sets. Leave the remaining answer in each set blank. a) 2,4-dinitrobenzoic acid: v p-nitrobenzoic acid: p-bromobenzoic acid: b) benzoic acid: v formic acid: v propanoic acid: c) cyclohexanol: v phenol: v benzoic acid:arrow_forwardThis structure has a lower pKa than usual because the conjugate base of the structure has unusual stability. Using the provided resonance structures, draw the curved electron-pushing arrows to show the deprotonation step. Then, draw the curved electron-pushing arrows to show the interconversion between resonance hybrid contributors. Be sure to account for all bond-breaking and bond-making stepsarrow_forward
