COMEDK · Chemistry · 26. Alcohols Phenols and Ethers
Arrange the following compounds in the decreasing order of their acidic strength.
(I) m-cresol
(II) Phenol
(III) m-aminophenol
(IV) m-methoxyphenol
- A I > II > III > IV
- B IV > III > II > I
- C I > III > IV > II
- D III > I > II > IV
Answer & Solution
Correct Answer
(B) IV > III > II > I
Step-by-step Solution
Detailed explanation
At meta position, only inductive effect (I-effect) operates, not resonance. m-methoxyphenol: \(-OCH_3\) has strong \(-I\) effect (O is highly electronegative) \(\to\) stabilizes phenoxide \(\to\) most acidic. m-aminophenol: \(-NH_2\) has \(-I\) effect but weaker than \(-OCH_3\)…
