In C6H5OH the lone pair of electrons on oxygen participates in resonance therby increasing the electron density of the ring thus activating the ring for electrophilic attack.Here seven atoms (six carbons of ring and oxygen of OH) are sharing eight electrons. In C6H5CH2OH the ring is activated like C6H5CH3 ( toluene) due to hyperconjugative effect, and additional negative inductive effect of O is also operating thus it is less active. |
