Chp.8 Alkene Reactions

H-X → H and X addition is in markovnikov positions, what does that mean?

X is added to MORE subbed carbon, while H is added to LEAST subbed carbon.

What does ROOR do for HX additions?

It causes the addition of H and X to occur in an anti-Markovnikov fashion, where X is added to the LEAST subbed carbon and H is added to the MORE substituted carbon.

H3O+ → (results in?)

Hydration of alkenes, leading to the addition of an -OH group and H, typically in Mark. positions.

1) Hg(OAc)2/H2O or CH3OH2) NaBH4 → (results in?)

Oxymercuration/demercuration which is the mark. addition of OH or RO in ANTI-PLANAR POSITION (THINK: OMA)

1) BH3/THF 2) H2OH/-OH → (results in?)

Hydroboration is the ANTI-mark addition of OH and is SYNPLANAR (=same). (THINK: HAS)

X2/CCl4 or CH2Cl2 → (results in?)

ANTI COPLANAR addition of halogens (Br, Cl, I)

X2/H2O → (results in?)

Mark. addition of OH in ANTIPLANAR position.
