    Which is a stronger acid, phenol or cresol? Explain.

    Answer:

                    Cresol is methyl phenol. It has three positional isomers : o-cresol, m-cresol and p-cresol. Due to \[+I\]-effect of \[C{{H}_{3}}\] group, electron-density in the \[O-H\] bond increases. Therefore, it becomes difficult to break the \[O-H\] bond as compared to that in phenol and hence all cresols are less acidic than phenol or phenol is a stronger acid than cresols. (Due to \[+I\]-effect of \[C{{H}_{3}}\] group, electron density in the \[O-H\] bond increases thereby making the cleavage of \[O-H\] bond difficult)
