A reaction involving the addition of two groups to a conjugated p system in which one group is installed at the C1 position and the other group is installed at the C4 position.
alpha (a) anomer
The cyclic hemiacetal of an aldose in which the hydroxyl group at the anomeric position is trans to the CH2OH
A high-energy molecular orbital resulting from the destructive interference between atomic orbitals.
atomic mass unit (amu)
A unit of measure equivalent to 1 g divided by Avogadro’s number.
The mass of an atom in atomic mass units. (3.1)
In IR spectroscopy, a type of vibration that generally produces a signal in the fingerprint region of an IR spectrum.
beta (b) position
The position immediately adjacent to an alpha (a) position.
The difference between the numbers of electrons in bonding molecular orbitals and antibonding molecular orbitals, divided by two. (10.7)
In a Lewis structure a pair of electrons that is shared by two atoms. (Section 9.2)
chemical shift (d)
In an NMR spectrum, the location of a signal, defined relative to the frequency of absorption of a reference compound, tetramethylsilane (TMS).
A compound inwhich two carbon-carbon p bonds are separated from each other by exactly one s bond.
The atom of a ligand that bonds to the metal. (Section 23.2)
A nonsuperimposable mirror image.
first law of thermodynamics
A statement that energy is conserved in any process. One way to express the law is that the change in internal energy, ?E, of a system in any process is equal to the heat, q, added to the system, plus the work, w, done on the system by its surroundings: ?E = q + w. (Section 5.2)
frequency factor (A)
A term in the Arrhenius equation that is related to the frequency of collision and the probability that the collisions are favorably oriented for reaction. (Section 14.5)
A protein, particularly rich in the basic amino acids lysine and arginine, that is found associated with DNA molecules
The observation that second-row elements (C, N, O, and F) will form the necessary number of bonds so as to achieve a full valence shell (eight electrons).
Matter that has a fixed composition and distinct properties. (Section 1.2)
A law stating that the partial pressure of a solvent over a solution, Psolution, is given by the vapor pressure of the pure solvent, P° solvent, times the mole fraction of a solvent in the solution, Xsolvent: Psolution = XsolventP° solvent. (Section 13.5)
An intermediate with tetrahedral geometry. This type of intermediate is formed when a nucleophile attacks the carbonyl group of a carboxylic acid derivative.
