Answer» tion:Q1 ) Benzene gives Electrophilic Substitution reaction easily but Nucleophilic Reaction with difficulty ? A1 ) Benzene is a planar coumpound ( which is one plane ) . It has delocalised electrons in it . These delocalised electrons makes it electron richAs it is electron rich , it ATTRACTS electron deficient species ( electrophiles ) towards it .Species which are electron rich ( nucleophiles ) feel a force of repulsion when try to come near benzene as benzene is ALSO electron richThis is why Benzene undergoes Electrophilic Substitution easily Q2 ) Benzene is having 3 double bonds but it mainly undergoes Electrophilic Substitution and not ADDITION Reaction ? A2 ) Benzene has 3 Double Bonds so we try Addition Reaction but that is wrongBenzene has 3 Double Bonds and they are conjugatedThis makes Benzene stable due to ResonanceDue to this Benzene becomes extremely stable and PREFERS to undergo Electeophilic Substituion and not Addition Reaction |
