Mansi Kaushal 8 years, 2 months ago

If an electrophile is substituted by another electrophile reaction is classified as electrophilic substitution. Benzene nucleus is nucleophile therefore undergoes electrophilic attack in slow step and in fast step base eliminates H+ to acquire aromaticity of benzene. Rate is directly proportional to nucleophilicity of benzene nucleus and electrophilicity of attacking electrophile. Group exhibiting +R effect and hyperconjugation called activating group. Group exhibiting -R effect and reverse hyperconjugation called deactivating group.
