1.	Explain why reactivity of benzene ring is increases due to presence of -OH group in phenol.
Answer» SOLUTION :According to above structure of phenol, ortho and para position of -OH possess negative charge MEANS HIGH density of electrons. So electrophilic group react on ortho and para position. (a) On resonance, electron PAIR of -OH group enter into the benzene ring, so electrophilic substitution reaction becomes easy in phenol with respect to benzene. (b) -OH group has -I effect, so it will ATTRACT electrons of ring towards itself. butstrengthof resonanceeffect` gt`strengthofinductiveeffect, soelectrondensityis moreinphenolis morereactivetowards. thebenzene ringof phenolis morereactivetowardselectrophilicreactionoccursat orthoand parapositionof -OHgroupalso-OHgroupis activatoin nature .
