activation energy (Ea).
The minimum amount of energy required to initiate a chemical reaction. (13.4)
Hydrocarbons containing one or more carbon–carbon double bonds. (Section 24.2)
In 13C NMR spectroscopy, a technique in which all 13C!1H splitting is suppressed with the use of two rf transmitters.
A band of molecular orbitals lying higher in energy than the occupied valence band and distinctly separated from it. (Section 12.7)
coordinate covalent bond.
A bond in which the pair of electrons is supplied by one of the two bonded atoms; also called a dative bond. (9.9)
The deterioration of metals by an electrochemical process. (18.7)
The spreading of electron density over a larger volume of space.
A barbed curved arrow used to show the change in position of a single electron.
An orbital that results from the mixing of different kinds of atomic orbitals on the same atom. For example, an sp3 hybrid results from the mixing, or hybridizing, of one s orbital and three p orbitals. (Section 9.5)
Compounds that contain only carbon, fluorine, and hydrogen (no chlorine).
hydronium ion 1H3O+2
The predominant form of the proton in aqueous solution. (Section 16.2)
The tendency of nonpolar groups to cluster so as to shield them from contact with an aqueous environment.
Hückel criteria for aromaticity
To be aromatic, a monocyclic compound must have one 2p orbital on each atom of the ring, be planar or nearly so, and have (4n 1 2) p electrons in the cyclic arrangement of 2p orbitals
The attractive forces between molecules.
Compounds whose molecules have the same overall composition but different structures. (Sections 2.9 and 23.4)
The gradual decrease in atomic and ionic radii with increasing atomic number among the lanthanide elements, atomic numbers 57 through 70. The decrease arises because of a gradual increase in effective nuclear charge through the lanthanide series. (Section 23.1)
An effect thatprevents the use of bases stronger than hydroxidewhen the solvent is water.
lithium dialkyl cuprate
A nucleophilic compound with the general structureR2CuLi.
Having no net overlap.
A double-helix model for the secondary structure of a DNA molecule
