MCQ
Phenol is more acidic than
  • A

  • B

  • C
    ${C_2}{H_2}$
  • ✓
    Both $(a)$ and $(c)$
✓

Answer

Correct option: D.
Both $(a)$ and $(c)$
d
(d) Methoxy group due to $+I$ effect increase electron density on $OH -$ group, thus making it less acidic. Thus $o-$ methoxy phenol and acetylene are less acidic than phenol, $p-$ nitrophenol is more acidic than phenol.
