A common non-SI unit of length, denoted Å, that is used to measure atomic dimensions: 1Å = 10-10 m. (Section 2.3)
Streams of electrons that are produced when a high voltage is applied to electrodes in an evacuated tube. (Section 2.2)
Atoms that lie in the same plane.
crossed aldol reaction
An aldol reaction that occurs between different partners.
A device in which a nonspontaneous oxidation–reduction reaction is caused to occur by passage of current under a sufficient external electrical potential. (Section 20.9)
Enantiomeric excess (ee)
The difference between the percentage of two enantiomers in a mixture
Enthalpy change, DH
The difference in total bond strengths and solvation between various points under comparison on a reaction coordinate diagram
A state of a system at higher energy than the ground state.
In Diels-Alder reactions that produce bicyclic structures, the positions that are anti to the larger bridge.
A complex whose electrons populate the d orbitals to give the maximum number of unpaired electrons. (Section 23.6)
Solids that are composed of metal atoms. (Section 12.1)
An allowed energy state of an electron in the quantum mechanical model of the atom; the term orbital is also used to describe the spatial distribution of the electron. An orbital is defined by the values of three quantum numbers: n, l, and ml (Section 6.5)
Pi (p) molecular orbital
A molecular orbital formed by overlapping parallel 2p orbitals on adjacent atoms; its electron density lies above and below the line connecting the atoms
A device that measures the rotation of plane-polarized light caused by optically active compounds.
A complex derived from the porphine molecule. (Section 23.3)
Elimination of two substituents at a metal center, causing the oxidation state of the metal to decrease by two.
Sharpless asymmetric epoxidation
A reaction that converts an alkene into an epoxide via a stereospecific pathway.
The study of the interaction between matter and electromagnetic radiation.
A reaction in which an atom or group of atoms in a compound is replaced by another atom or group of atoms.
Williamson ether synthesis
A method for preparing an ether from an alkoxide ion and an alkyl halide (via an SN2 process).
