-
what is regiochemistry?
which part of the reagent adds to which end of the double bond in an addition reaction
-
Only during free radical addition of HBr does ____ ________ addition take place
anti markovnikov
-
Explain why in the following reaction Br goes to the less substituted carbon:
because a tertiary free radical carbon is more stable than a secondary free radical carbon
-
During oxymercuration-demurcuration, Hg(OAc)2 acts as a what? (electrophile or nucleophile
electrophile
-
in oxy-demurc., when Hg(OAc)2 becomes Hg(OAc) and forms two bonds with the substrate, what molecule does it form?
it forms a mercurinium ion
-
During oxy-demurc. which carbon does the H2O attack?
the more substituted carbon
-
alkoxymercuration-demurc takes place in a(n) ____ _____
alcohol solvent
-
In alkoxy-demurc., the alcohol forms a(n) ____ on the substrate
ether
-
does rearrangement occur during oxymercuration-demurc?
no
-
is hydroboration-oxidation markovnikov or anti-mark?
anti-mark
-
hydroboration occurs in ___ step(s), so therefore there is/isn't rearrangement
one step so therefore there isn't rearrangement
-
during hydroboration, the boron atom adds to the ____ substituted part of the double bond and the hydrogen adds to the ____ substituted part of the double bond
less, more
-
what is the hydroboration mechanism?
-
__ moles of alkene can react with each mole of BH3
