Question

Arrange the following in increasing acidic strength
Propan-1-ol ; 2,4,6-Trinitrophenol ; Nitrophenol ; 3,5- Dinitrophenol ; Phenol ; 4-Methyl phenol

Answer 1

3,5- Dinitrophenol> 2,4,6-Trinitrophenol> Nitrophenol >Propan-1-ol >4-Methyl
phenol.

because 3,5- Dinitrophenol is a not stable then 2,4,6-Trinitrophenol in no2 is electron attractive group.then the o- Nitrophenol or p- Nitrophenol and in the 4-Methyl phenol is the + R affect of ch3.

thanks for asking good question.
