acid-dissociation constant (Ka)
An equilibrium constant that expresses the extent to which an acid transfers a proton to solvent water. (Section 16.6)
A compound containing a !CHO group
aldol addition reaction
A reaction that occurs when an aldehyde or ketone is attacked by an enolate ion. The product of an aldol addition reaction is always a b-hydroxy aldehyde or ketone.
An atom or group of atoms bearing a positive charge.
In electrocyclic reactions,a type of rotation in which the orbitals being used to form the new s bond must rotate in the same way.
A lone pair or charge that is participating in resonance.
In NMR spectroscopy,protons or carbon atoms whose surrounding electron density is poor.
A state of balance in which opposing processes occur at the same rate. (Section 11.5)
Fischer esterifi cation
The process of forming an ester by refl uxing a carboxylic acid and an alcohol in the presence of an acid catalyst, commonly H2SO4, ArSO3H, or HCl
A barbed curved arrow used to show the change in position of a single electron.
Heterocyclic aromatic amine
An amine in which nitrogen is one of the atoms of an aromatic ring.
A tentative explanation of a series of observations or of a natural law. (Section 1.3)
Compounds formed between two different halogen elements. Examples include IBr and BrF3. (Section 22.4)
A group of molecules arranged in a sphere such that the surface of the sphere is comprised of polar groups, rendering the micelle water soluble.
A reaction in which a nucleophile attacks a conjugated p system, resulting in a 1,4-addition.
In a Lewis structure a pair of electrons assigned completely to one atom; also called a lone pair. (Section 9.2)
plane of symmetry
A plane that bisects a compound into two halves that are mirror images of each other.
Refers to two hydrogens bonded to a carbon atom. When a different atom replaces one or the other, the carbon becomes a chiral center. The hydrogens of the CH2 group of ethanol, for example, are prochiral. Replacing one of them by deuterium gives (R)-1-deuteroethanol; replacing the other gives (S)-1-deuteroethanol
A substitution reaction in which the solvent functions as the nucleophile.
sp Hybrid orbitaL
A hybrid atomic orbital formed by the combination of one s atomic orbital and one 2p atomic orbital.
