What is hyperconjugation in alkenes?

The perfect alignment of neighboring C-H sigma bonds with pi bonds

What orientation of the highest priority substituents is associated with E configuration?

Opposite

What orientation of the highest priority substituents is associated with Z configuration?

Same

Why are trans alkenes more stable than cis alkenes?

The substituents in a cis alkene will interact, resulting in steric strain

Is hydrohalogenation exothermic or endothermic?

Exothermic

What is Markovikov’s rule?

The more stable carbocation will form, so X- adds to the more substituted carbon.

What compound is absolutely required for acid-catalyzed hydration?

H2O or OH

hydrohalogenation (electrophilic addition of H-X)

acid-catalyzed hydration

Oxymercuration/Demercuration

Hydroboration/Oxidation

What is a syn addition?

When 2 substituents react on the same side of a compound

Halogenation

Halohydrin Formation

Hydrogenation of Alkenes
