Question:
The carboxylic acid with highest $pK_a$ and lowest $pK_a$ values of the following respectively are:
The carboxylic acid with highest $pK_a$ and lowest $pK_a$ values of the following respectively are:
Show Hint
Electron-withdrawing groups decrease \(pK_a\), increasing acidity; electron-donating groups increase \(pK_a\), decreasing acidity.

Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The carboxylic acid with electron-donating group (III, methyl) has the highest \(pK_a\) (weakest acid), and that with strong electron-withdrawing group (IV, nitro) has the lowest \(pK_a\) (strongest acid).
