Which one of the following is most reactive toward electrophilic reagent?
Answer»
SOLUTION :Electron DONATING effect DECREASES in the order `-OHgt-OCH_(3)gt-NHCOCH_(3)gt-CH_(3)gt-CH_(2)OH`. Therefore, `-OH` group is most strongly electron donating group and hence (B) i.e., o-cresol is most reactive towards electrophilic reagent.
