A carbon atom adjacent to a carbonyl group
An object that lacks chirality; an object that has no handedness
acidic anhydride (acidic oxide)
An oxide that forms an acid when added to water; soluble nonmetal oxides are acidic anhydrides. (Section 22.5)
A compound that possesses a hydroxyl group (OH).
alkaline earth metals
Members of group 2A in the periodic table. (Section 7.7)
Carboxyl group (Section 1.3D)
A !COOH group.
A bond that results when two atoms share a pair of electrons.
A measure of a solvent’s ability to insulate opposite charges from one another
directed aldol addition
A techniquefor performing a crossed aldol addition thatproduces one major product.
electrostatic potential maps
A three-dimensional, rainbowlike image used to visualize partial charges in a compound.
A push or a pull. (Section 5.1)
A charge associated with any atom that does not exhibit the appropriate number of valence electrons.
Atoms or groups on an atom that give an achiral molecule when one of the groups is replaced by another group. The hydrogens of the CH2 group of propane, for example, are homotopic. Replacing either one of them with deuterium gives 2-deuteropropane, which is achiral. Homotopic groups have identical chemical shifts under all conditions
A reaction with water. When a cation or anion reacts with water, it changes the pH. (Sections 16.9 and 24.4)
A form of isomerism in which the two forms of a compound (stereoisomers) are nonsuperimposable mirror images. (Section 23.4)
The net movement of solvent through a semipermeable membrane toward the solution with greater solute concentration. (Section 13.5)
A crystal lattice in which the lattice points are located only at the corners of each unit cell. (Section 12.2)
A solvent that is a hydrogen-bond donor. Common protic solvents are water, low-molecular-weight alcohols, and low-molecular weight carboxylic acids.
For a chiral compound that is subjected to plane-polarized light, the observed rotation when a standard concentration (1 g/mL) and a standard path length (1 dm) are used.
Williamson ether synthesis
A method for preparing an ether from an alkoxide ion and an alkyl halide (via an SN2 process).
