-
Solution
Among the following four compounds
(i)phenol
(ii)methylphenol
(iii)meta-nitrophenol
(iv)para-nitrophenol the acidity order is :
-
Solution
-
Solution
Phenol is most acidic because its conjugate base is stabilised due to resonance, while the rest three compounds are alcohols, hence, their corrosponding conjugate bases do not exhibit resonance.
