Full solutions for Chemistry: The Central Science | 13th Edition
amino acid residue
The individual repeating units in a polypeptide chain or protein.
An atom or group of atoms bearing a negative charge.
Avogadro’s number (NA).
6.022 3 1023; the number of particles in a mole. (3.2)
A unit of pressure equal to 105 Pa. (Section 10.2)
A compound containing a metal ion bonded to a group of surrounding molecules or ions that act as ligands. (Section 23.2)
The number of adjacent atoms to which an atom is directly bonded. In a complex the coordination number of the metal ion is the number of donor atoms to which it is bonded. (Sections 12.37 and 24.2)
A complex polymer resulting from the polymerization of two or more chemically different monomers. (Section 12.8)
The angle created by two intersecting planes.
Two mirror-image molecules of a chiral substance. The enantiomers are nonsuperimposable. (Section 23.4)
A reaction in which the reaction rate is proportional to the concentration of a single reactant, raised to the first power. (Section 14.4)
A graphic method for determining the relative energies of p MOs for planar, fully conjugated, monocyclic compounds.
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.
Water that contains appreciable concentrations of Ca2 + and Mg 2 + ; these ions react with soaps to form an insoluble material. (Section 18.4)
On an aromatic ring, the C3 position.
In NMR spectroscopy, a technique in which only the one-bond couplings are observed. CH3 groups appear as quartets, CH2 groups appear as triplets, CH groups appear as doublets, and quaternary carbon atoms appear as singlets.
A group that directs the regiochemistry of an electrophilic aromatic substitution reaction such that the incoming electrophile is installed at the ortho or para positions.
The extent to which atomic orbitals on different atoms share the same region of space. When the overlap between two orbitals is large, a strong bond may be formed. (Section 9.4)
Polymers made up of repeating monosaccharide units linked together by glycoside bonds.
A process by which one or more compounds are removed from a mixture of organic compounds, based on a difference in solubility and/or acid-base properties.
A polymer with alternating R and S confi gurations at the chiral centers along its chain, as, for example, syndiotactic polypropylene
