Question
o-nitrophenol is more acidic than o-methoxyphenol.

Answer

-R and -I effect of -NO2 group decreases the electron density in O-H bond and make loss of proton easy in O-nitrophenol whereas +R effect of -OCH3 group increases the electron density in O-H bond and makes release of proton difficult in o-methoxyphenol. That is, why o-nitrophenol is stronger acid than o-methoxyphenol.
