Key Concepts

Catalytic Hydrogenation

This concept refers to the addition of hydrogen (H2) across a double bond in the presence of a metal catalyst like palladium. It is a reaction where the alkene is converted into an alkane via a syn addition mechanism, meaning that both hydrogen atoms add to the same side of the molecule.

Electrophilic Addition

This is a fundamental reaction mechanism for alkenes, where an electrophile (such as Br2) reacts with the electron-rich double bond. The mechanism typically involves the formation of an intermediate cyclic halonium ion, followed by nucleophilic attack by a halide ion, resulting in anti addition to produce a vicinal dihalide.

Acid-Catalyzed Hydration

This reaction involves the addition of water to an alkene in the presence of an acid catalyst (like H2SO4). The mechanism proceeds through the formation of a carbocation intermediate, and the addition of water follows Markovnikov's rule, where the hydroxyl group attaches to the more substituted carbon, resulting in the formation of an alcohol.
