Which option /options are correct?: Electrophilic substitutions include reactions of benzene: A., with concentrated sulfuric acid B., with hydrogen in the presence of HCl C., with chlorine in the presence of FeCl D., in which aromatic character is formed
Accepted Answer
Correct options are:
A., with concentrated sulfuric acid
C., with chlorine in the presence of FeCl
Electrophilic substitution reactions are those reactions in which an electrophile (a species that is attracted to electrons) attacks a double bond and replaces one of the atoms in the double bond. In the case of benzene, the electrophile is typically a positive ion, such as H+, or a molecule that can easily form a positive ion, such as FeCl3. The electrophile attacks the benzene ring and forms a new bond to one of the carbon atoms in the ring, while the hydrogen or chlorine atom that was originally bonded to that carbon atom is lost. Aromatic character is preserved in these reactions because the benzene ring retains its six-membered ring structure and its three double bonds.
