Key Concepts

Markovnikov’s Rule

Markovnikov's rule guides the regiochemistry of electrophilic addition reactions to alkenes. It predicts that in the addition of HX to an unsymmetrical alkene, the hydrogen atom will attach to the carbon with more hydrogen substituents, resulting in a more stable carbocation intermediate which then reacts with the halide ion.

Regiochemistry

Regiochemistry deals with the orientation of chemical bond formation in a reaction. In the context of hydrohalogenation, it determines which carbon of the double bond receives the hydrogen and which one gains the halogen, thereby influencing the structure of the final product.

Electrophilic Addition

This is a fundamental reaction mechanism in organic chemistry where a reagent such as HBr adds across a carbon–carbon double bond. During the reaction, the alkene acts as a nucleophile, attacking the electrophilic proton of HBr, which leads to the formation of a carbocation intermediate that subsequently captures a bromide ion.
