    Nucleophilic Aromatic Substitution: Elimination–Addition01:11

    Nucleophilic Aromatic Substitution: Elimination–Addition

    Simple aryl halides do not react with nucleophiles. However, nucleophilic aromatic substitutions can be forced under certain conditions, such as high temperatures or strong bases. The mechanism of substitution under such conditions involves the highly unstable and reactive benzyne intermediate. Benzyne contains equivalent carbon centers at both ends of the triple bond, each of which is equally susceptible to nucleophilic attack. This 50–50 distribution of products is confirmed through isotopic...

    Reactions at the Benzylic Position: Halogenation

    Benzylic halogenation takes place under conditions that favor radical reactions such as heat, light, or a free radical initiator like peroxide.
    Hydrolysis of Chlorobenzene to Phenol: Dow Process01:10

    Hydrolysis of Chlorobenzene to Phenol: Dow Process

    Simple aryl halides do not react with nucleophiles under normal conditions. However, the reaction can proceed under drastic conditions involving high temperatures and high pressure to give the substituted products. For example, chlorobenzene is converted to phenol using aqueous sodium hydroxide at 350 °C under high pressure by the Dow process. The reaction follows an elimination-addition mechanism involving a benzyne intermediate. Here, the chloride ion is eliminated to generate the benzyne...
    Electrophilic Aromatic Substitution: Nitration of Benzene01:20

    Electrophilic Aromatic Substitution: Nitration of Benzene

    The nitration of benzene is an example of an electrophilic aromatic substitution reaction. It involves the formation of a very powerful electrophile, the nitronium ion, which is linear in shape. The reaction occurs through the interaction of two strong acids, sulfuric and nitric acid.
    Formation of Halohydrin from Alkenes02:41

    Formation of Halohydrin from Alkenes

    An alkene, such as propene, reacts with bromine in the presence of water to yield a halohydrin. Halohydrins contain a halogen and a hydroxyl group attached to adjacent carbons. When the halogen is bromine, it is called a bromohydrin, while a chlorohydrin has chlorine as the halogen.
    Electrophilic 1,2- and 1,4-Addition of HX to 1,3-Butadiene01:17

    Electrophilic 1,2- and 1,4-Addition of HX to 1,3-Butadiene

    The electrophilic addition of hydrogen halides such as HBr to alkenes and nonconjugated dienes gives a single product as per Markovnikov’s rule.
