AP EAMCET · Chemistry · Carboxylic Acid Derivatives
The carboxylic acid with highest \(\mathrm{pK}_{\mathrm{a}}\) and lowest \(\mathrm{pK}_{\mathrm{a}}\) values of the following respectively are
- A I, II
- B I, IV
- C III, II
- D III, IV
Answer & Solution
Correct Answer
(D) III, IV
Step-by-step Solution
Detailed explanation
Relative acidity: Electron-withdrawing groups (-I) increase acidity; electron-donating groups (+I) decrease acidity. Order of acidity (strongest to weakest): \(\mathrm{ClCH_2COOH}\) (III) (\(-I\) effect) \(\gt \mathrm{HCOOH}\) (IV) (no \(\pm I\)) \(\gt \mathrm{CH_3COOH}\) (I)…
