In phenol, C−O bond is less polar due to the electron-withdrawing effect of benzene ring whereas, in methanol, C−O bond is more polar due to electron-releasing effect of −CH 3 group.

In phenol, there is double bond character between C—O bond and there is +ve charge on oxygen due to electron withdrawing benzene ring, therefore, dipole moment is less whereas in methanol there is no such positive charge, it has more dipole moment than phenol.

wo attached group pe depend kr kayenge kyunki methanol ke case me OH ke -I effect ke wajah se oxygen pe negative or carbon pe positive charge aa rhe hai isiliye jyada polar h

phenol ke case me delocalisation ho ja rhe or polarity km ho ja rhe h
