Key Concepts

Acid-Catalyzed Hydration

This is a reaction in which water is added to an alkene in the presence of an acid catalyst. The mechanism relies on protonation of the double bond to generate a carbocation intermediate, followed by nucleophilic attack by water and a subsequent deprotonation step to form an alcohol.

Electrophilic Addition Mechanism

This concept describes a two-step process where an electrophile, typically a proton from an acid, adds to the electron-rich double bond of an alkene to form a carbocation, which is then attacked by a nucleophile. The overall reaction converts the alkene into a saturated compound with added functional groups.

Markovnikov's Rule

Markovnikov's Rule predicts that in electrophilic additions to unsymmetrical alkenes, the hydrogen atom will add to the carbon with more hydrogen atoms, leading to the formation of the more stable carbocation intermediate on the more substituted carbon, which directs the regioselectivity of the reaction.

Carbocation Stability

The formation and stability of carbocation intermediates are central to many acid-catalyzed reactions. More substituted carbocations, such as tertiary over secondary or primary, are stabilized by electron-donating alkyl groups, and this stability heavily influences the outcome of the reaction by determining which intermediate forms preferentially.
