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. Rearrangements are possible. This reaction follows Markovnikov’s rule. KNOW THIS MECHANISM
*I also went over cationic polymerization

Addition of a weak acid

Acid-catalyzed hydration: H2SO4/H2O. Goes through a carbocation intermediate so rearrangements are possible. The electrophile (H+) adds to the least substituted carbon, and water acts as a nucleophile adding to the carbocation on the more substituted carbon. The end product is an alcohol. This reaction follows Markovnikov’s rule.-Know this mechanism.
Remember the nucleophile can also be an alcohol and that will result in the production of an ether.
