What is electrophilic substitution?
A substitution reaction in which the first step is attack by an electrophile. Electrophilic substitution is a feature of reactions of benzene (and its compounds) in which a positive ion approaches the delocalized pi electrons on the benzene... Read More »

What is electrophile substitution reaction?
An electophile substitution reaction, is a reaction in which an electrophile (electron/negative charge loving species) replaces a substituent on an another compound; the electrophile attacks the compund because its attracted to the compound... Read More »
