Alcohols
|
Compounds that have their -OH group bonded to a saturated, sp^3 hybridized carbon atom.
|
|
Enols
|
Compounds that have their -OH group bonded to a vinylic sp^2 hybridized carbon atom.
|
|
Alcohols and phenols are both ________ acidic and basic.
|
weakly
|
|
Alkoxide ion
|
The anion (RO-) formed by deprotonation of an alcohol.
|
|
Phenoxide Ion
|
ArO-
|
|
A smaller Ka means a compound is _________ acidic.
|
less
|
|
A smaller pKa means a compound is ________ acidic.
|
more
|
|
Thiols
|
The sulfur analogs of alcohols. A compound containing the -SH functional group.
|
|
Carbanions
|
A carbon anion, or subtance that contains a trivalent, nagatively charged carbon atom (R3:C-). Carbanions are sp3-hybridized and have eight electrons in the outer shell of the negatively charged carbon.
|
|
Sn1 Reaction
|
A unimolecular nucleophilic substitution reaction.
|
|
Sn2 Reaction
|
A bimolecular nucleophilic substitution reaction.
|
|
E1 Reaction
|
A unimolecular elimination reaction in which the substrate spontaneously dissociates to give a carbocation intermediate, which loses a proton in a separate step.
|
|
Phosphorus Oxychloride
|
POCl3
|
|
Zaitsev's Rule
|
A rule stating that E2 elimination reactions normally yield the more highly substituted alkene as a major product.
|
|
Cromium Trioxide
|
CrO3
|
|
Protecting Group
|
A group that is introduced to protect a sensitive functional group toward reaction elsewhere in the molecule. After serving its protective function, the group is removed.
|
|
Quinone
|
It's a 2,5-cyclohexadiene-1,4-dione.
|
|
Hydroquinone
|
It's a 1,4-dihydroxybenzene.
|
|
E1cB Reaction
|
A unimolecular elimination reaction in which a proton is first removed to give a carboanion intermediate, which then expels the leaving group in a separate step.
|
|
E2 Reaction
|
A bimolecular elimination reaction in which both the hydrogen and the leaving group are lost in the same step.
