- C IV \( \lt \) II \( \lt \) I \( \lt \) III
- D IV \( \lt \) III \( \lt \) II \( \lt \) I
Answer & Solution
Correct Answer
(C) IV \( \lt \) II \( \lt \) I \( \lt \) III
Step-by-step Solution
Detailed explanation
\(\Rightarrow\) Greater the \(\mathrm{pK}_{\mathrm{a}}\) value lesser will be its acidic nature. \(\Rightarrow\) Electron withdrawing group increase acidic nature. Order of acidic nature \(\mathrm{IV}\gt\mathrm{II}\gt\mathrm{I}\gt\mathrm{III}\) Order of…
