Chlorination of chloroform with chlorine
WebThe formation of the electrophile. Many of the electrophilic substitution reactions of benzene involve an attack on the benzene by a positive ion. In the chlorine case, forming a Cl + ion needs too much energy. As the chlorine molecule approaches a benzene ring, the delocalised electrons in the ring repel the electrons in the chlorine-chlorine ...
