MCQ
Which of the following is most acidic
- APhenol
- BBenzyl alcohol
- ✓$m-$ chlorophenol
- DCyclohexanol
✓
Answer
Correct option: C.
$m-$ chlorophenol
c
(c) Benzyl alcohol and cyclohexanol are not acidic while phenol and $m-$ chlorophenol are acidic due to presence of electron withdrawing groups like
(c) Benzyl alcohol and cyclohexanol are not acidic while phenol and $m-$ chlorophenol are acidic due to presence of electron withdrawing groups like
$ - N{O_2},\,\, - Cl,\,\, - CN$
increases the acidic character of phenols. Hence, $m-$chlorophenol is more acidic than phenol.
