" 4-nitrophenol is more acidic than "4" -methylphenol.Give reason "

Explain why p-nitrophenol is more acidic than phenol ?

Give possible explanation for the following. (a) Ortho-nitrophenol is more acidic than ortho-methoxyphenol. (b) Alcohols are easily protonated in comparision to phenols. (c) The relative ease of dehydration of alcohols is : tertiary gt secondary gt primary.

Assertion (A): 2,6-Dimethyl-4-nitrophenol (I) is more acidic than 3,5-dimethyl-4-nitrophenol (II). Reason (R ): It is due to the steric inhibition of the resonance of (-NO_(2)) group with two (Me) groups in (II).

Assertion (A) p-nitrophenol is more acidic than phenol. Reason (R) Nitro group helps in the stabilisation of the phenoxide ion by dispersal of negative charge due to resonance.
