In the folowing compounds
The order of acidity is :
The order of acidity is :
Options
A.III > VI > I > II
B.II > I > II > IV
C.II > I > III > IV
D.IV > III > I > II
Solution
(i) All the four acidic nature due to heterolysis of phenoli - O - H group.
(ii) Any electron releasing group will secreases the acidic strength, the (II) will be less acidic than phenol.
(iii) - NO2 gp . is rlrctron with drawing and so increases the acidic strength. Electron pulling effect is more at p-position than -position. That why p-nitrophenol (IV) is most acidic. Thus, order of acidic strength is IV > III > I > II
