absolute temperature scale.
A temperature scale that uses the absolute zero of temperature as the lowest temperature. (5.3)
A ligand in which two linked coordinating atoms are bound to a metal. (Section 23.3)
A polymer that contains a large number of branches connected to the main chain of the polymer.
A reaction in which two or more substances combine to form a single product. (4.4)
A material that can undergo a substantial change in shape via stretching, bending, or compression and return to its original shape upon release of the distorting force. (Section 12.6)
A technique for separating amino acids from each other based on a difference in pI values.
The energy released when 1 g of a substance is combusted. (Section 5.8)
A method forpreparing primary amines that avoids formation of secondary and tertiary amines.
Gibbs free energy change (DG°)
The energy that dictates the position of chemical equilibria and rates of chemical reactions. A thermodynamic function of enthalpy, entropy, and temperature, given by the equation DG° 5 DH° 2 TDS°. If DG° , 0, the position of equilibria for the reaction favors products. If DG° . 0, the position of equilibria favors reactants.
A compound containing a hydroxyl group (OH) and an alkoxy group (OR) connected to the same carbon atom.
ignal splitting in NMR
Spin-spin coupling with adjacent nuclei split NMR signals depending on the extent of coupling and the number of adjacent equivalent nuclei.
A spectrum that contains radiation at only certain specific wavelengths. (Section 6.3)
A measure of the force exerted on a unit area. In chemistry, pressure is often expressed in units of atmospheres (atm) or torr: 760 torr = 1 atm; in SI units pressure is expressed in pascals (Pa). (Section 10.2)
A positively charged subatomic particle found in the nucleus of an atom. (Section 2.3)
The determination of the presence or absence of a particular substance in a mixture. (Section 17.7)
Elimination of two substituents at a metal center, causing the oxidation state of the metal to decrease by two.
representative (main-group) element
An element from within the s and p blocks of the periodic table (Figure 6.29). (Section 6.9)
retro Diels-Alder reaction
The reverse of a Diels-Alder reaction, achieved at high temperature. A cyclohexene derivative is converted into a diene and a dienophile.
In IR spectroscopy, atype of vibration that generally produces a signal in the diagnostic region of an IR spectrum.
A geometry adopted by an atom with a steric number of 3. All three groups lie in one plane and are separated by 120°.
