Key Concepts

Electrophilic Addition Reaction

This concept involves the reaction of an electrophile with a nucleophilic double bond, where the pi electrons of an alkene attack the electrophile, leading to the addition of substituents across the double bond. In the case of alkenes reacting with hydrogen halides, the alkene acts as a nucleophile and the hydrogen as an electrophile, initiating the reaction.

Carbocation Intermediate Formation

During the electrophilic addition of HCl to an alkene like cyclohexene, the addition of the proton (H?) to the alkene generates a carbocation intermediate. This step is crucial because the stability of the intermediate largely influences the reaction pathway and outcome. The positive charge on the carbocation is typically stabilized by the adjacent alkyl groups or through resonance in more complex molecules.

Markovnikov's Rule

Markovnikov's rule is a guiding principle for the regiochemistry of electrophilic addition reactions. It states that when a hydrogen halide adds to an unsymmetrical alkene, the hydrogen atom attaches to the carbon with more hydrogen substituents while the halide attaches to the more substituted carbon. This rule explains the regioselectivity observed in the formation of the carbocation intermediate and ultimately the product distribution.
