Question: Rank these acids according to their expected pKa values. Highly electronegative atoms stabilize the conjugate base, making deprotonation occur more readily (stronger acid, lower pKa). Increasing the number of electronegative atoms further lowers pKa as does decreasing the distance between the electronegative atoms and the site of deprotonation.So H3O+ has a higher pKa value than H-Cl, therefore H3O+ is not as strong of an acid, or we could say it the other way around. H-Cl has a lower value for the pKa, therefore H-Cl is a stronger acid than H3O+. Alright, let's look at some more examples for acids and pKa values. So next let's look at acetic acid. So this compound right here.

In this case, we need to rank these acids according to their expec And clearly, given this expression, STRONGER acids, i.e. those acids for which the equilibrium lies to the RIGHT as we face the page, have inherently high #K_a# values. You have got #HClO_4#, #"perchloric acid"#, which is an exceptionally strong Bronsted acid, which would be stoichiometric in #H_3O^+# and #ClO_4^(-)#.This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Rank these acids according to their expected PKa values. CH3CH2COOH, ClCH2CH2COOH, Cl2CHCOOH, ClCH2COOH. Rank these acids according to their expected PKa values. Question: Rank these acids according to their The expected pKa values of the acids listed, in in Mar 20, 2018 · Explanation: Rank these acids according to their expected pKa values. ClCH2COOH ClCH2CH2COOH CH3CH2COOH Cl2CHCOOH In order of highest pka to lowest pka Concepts and reason PKa is the negative logarithm of dissociation constant. It gives the relative strengths of the acids. Stronger acids have smaller pKa values and weak acids have larger pKa value. The order of pKa values from highest to lowest is:. Cl2CHCOOH > Step 1 1 of 8 In this exercise, we need to rank the given acids based on their pK a values. Step 2 2 of 8 First, let us explain what the pK a values is and its trend: it is a measure of the acidity or basicity of a compound. It is the negative logarithm of the acid dissociation constant (K a) of an acid in a solution. Phosphoric acid, H_3PO_4 , is tribasic with pKa vaTranscribed Image Text: t the following bases in order fromGet the detailed answer: Rank these acid A lower pKa value indicates a stronger acid, as it dissociates more readily in water to release hydrogen ions. The alkyl chain length and the presence of functional groups can influence the pKa value of an acid. In this case, the longer the alkyl chain, the higher the pKa value. Therefore, The expected pKa values of the acids listed, in ... An application of the Henderson-Hasselbach Equation Answer: CH₃CH₂CH₂COOH > CH₃CH₂COOH > ClCH₂CH₂COOH > ClCH₂COOH. Explanation: Electron-withdrawing groups (EWGs) increase acidity by inductive removal of electrons from the carboxyl group.. Electron-donating groups (EDGs) decrease acidity by inductive donation of electrons to the carboxyl group.. The closer the substituent is to the carboxyl group, the greater is its effect.
