Practicing Success
Arrange the following compounds in increasing order of their acid strength: (A) Propan-1-ol (B) 3-nitrophenol (C) 3,5-Dinitrophenol (D) Phenol (E) 4-Methylphenol Choose the correct answer from the options given below: |
A < D < C < B < E C < B < D < E < A A < B < C < D < E A < E < D < B < C |
A < E < D < B < C |
Alcohols and phenols are electron-rich compounds and when any electron-withdrawing group is attached, their acidity increases. Alkyl groups show +I effect and -NO2 group show -M effect. Acidic nature of electron-withdrawing groups are as follows: Dinitro- > nitro > Phenyl > methyl > hydride |
