Question
Explain why is ortho nitrophenol more acidic than ortho methoxyphenol?
✓
Answer
Ortho nitrophenol is more acidic than ortho methoxyphenol because nitro group is an electron withdrawing and it will increase + ve charge on the oxygen atom to make it more acidic whereas $- OCH _3$ group is an electron releasing group and it will decrease + ve charge on the oxygen atom, thus making it less acidic and hence the $O - H$ bond will not break easily.
