Alkene Reactions Practice

Vocabulary and reaction mechanism details for various alkene additions, including reagents and regioselectivity.

Hydrohalogenation

The reaction of an alkene + $H-X$ where $X = \{a, Br, 1\}$.

Catalytic Hydrogenation

The addition of $H_2$ to an alkene using a metal catalyst, which involves syn addition and can result in a meso compound or an enantiomer.

Halogenation, halhydrin formation

A process involving nucleophilic attack ($nucattack$) with $X_2$ and $H_2O$ to create a substituted alkene.

Acid-catalyzed hydration of alkenes

A three-step mechanism: 1. Pronate ($H_3O^+$), 2. attack, 3. depronate.

Oxymercuration-Demercuration

A reaction using $Hg(OAc)_2$ that results in no rearrangement.

Hydroboration Oxydation

A reaction using reagents $BH_3 \cdot THF$ and $H_2O_2, NaOH$ that places an $OH$ group on the less substituted position (anti-Mark).
