1.	Which of the following are less acidic than phenol ?
Answer» `H_(2)O` o-Cresol p-Nitrophenol o-Nitrophenol Solution :Water `(pK_(a)=14)` is less acidic than phenol `(pK_(a) -= 8)`. PRESENCE of electron donating GROUP (methyl) in o-cresol makes it less acidic than phenol. Presence of electron with drawing group (nitro) in p- and o-nitrophenol MAKE them more acidic than phenol.
