Term
Why does the addition to an olefin occur?
Definition
s bonds stronger than p bonds
Term
Markovnikov’s Rule
Definition
during the ionic addition of an
unsymmetrical reagent to a double bond, the + portion of the adding reagent attaches itself to the
carbon atom of the double bond so as to yield the more stable carbocation
Term
What is a purpose of Oxymercuration
Definition
used to avoid carbocation rearrangements when adding H2O to an alkene
Term
Hydroboration can be best describes as
Definition
BH3 readily adds to alkenes, many synthetic uses for resulting organoborane
Term
How does hydroboration add to less sterically hindered olefinic carbon?
Definition
it yields anti-Markovnikov products
Term
When we say hydroboration is stereoselective...
Definition

Term
Given a choice, H2O attacks atom with...
Definition
greater + charge
Term
Carbenes are best summed up as
Definition
divalent carbon species; highly electrophilic due to incomplete octet
Term
What typically happens in the reactions of carbenes?
Definition
The carbene adds to a multiple bond.
Term
Alkenes can be oxidized with peroxycarboxylic acids, RCO3H, to give ...
Definition
oxacyclopropanes
