- Please answer this Can you give examples to explain Addition reactions-general characteristics Benzene rings do not reactthi like alkenes Remember, the electrophile adds to the less substituted carbon, and the nucleophile to the more substituted carbon. Markovnikov’s Rule: The addition of a hydrogen halide to an alkene favors the product in which the proton adds to the alkene carbon that is initially bonded to the greater number of hydrogen atoms. Carbocation rearrangements- Methyl groups and hydride groups can migrate to make a more stable carbocation. A primary carbocation is less stable than a secondary carbocation, which is less stable than a tertiary carbocation. Addition of A Strong Bronsted Acid Hydrohalogenation HX addition to an alkene. Goes through a carbocation intermediate. The electrophile (H+) adds to the less substituted carbon, and the carbocation forms on the more substituted carbon. The nucleophile (X-) then adds to the more substituted carbocation.…Item 2 Draw the organic products formed in each reaction. Consider both substitution and elimination products, if possible.
