The correct order of acid strength of the following compounds is :–

Answer 1

Hi there,

p-Nitrophenol > m-Nitrophenol > Phenol > p-Cresol

Why p-Nitrophenol is most acidic

p-Nitrophenol is a phenolic compound where the Nitro group is attached to the benzene ring exact opposite to Hydroxy group. We know that the Nitro group is an Electron withdrawing group. So it reduces the density of Electrons on the OH bond attached to the benzene ring.
