Full solutions for Organic Chemistry, | 9th Edition
Theoretically the lowest attainable temperature. (5.3)
activation energy (Ea).
The minimum amount of energy required to initiate a chemical reaction. (13.4)
Energetic electrons emitted from the nucleus, symbol 0-1e or b-. (Section 21.1)
Carboxyl group (Section 1.3D)
A !COOH group.
The electrode at which reduction occurs. (18.2)
An equation that uses chemical symbols to show what happens during a chemical reaction. (3.7)
continuous-wave (CW) spectrometer
An NMR spectrometer that holds the magnetic field constant and slowly sweeps through a range of rf frequencies, monitoring which frequencies are absorbed.
coupling (of protons)
A phenomenon observed most commonly for nonequivalent protons connected to adjacent carbon atoms in which the multiplicity of each signal is affected by the other.
A crystal lattice in which the lattice points are located at the faces and corners of each unit cell. (Section 12.2)
The number of valence electrons in an isolated atom minus the number of electrons assigned to the atom in the Lewis structure. (Section 8.5)
Spin-spin coupling that occurs between nonequivalent H atoms bonded to the same C atom. The H atoms are generally nonequivalent owing to restricted bond rotation in the molecule
The mixing of different types of atomic orbitals to produce a set of equivalent hybrid orbitals. (Section 9.5)
Radiation that has sufficient energy to remove an electron from a molecule, thereby ionizing it. (Section 21.9)
An assembly of a metal ion and the Lewis bases bonded to it. (Section 23.2)
A CH2 group.
A system of measurement used in science and in most countries. The meter and the gram are examples of metric units. (Section 1.4)
The specifi c rotation of a mixture of enantiomers divided by the specifi c rotation of the enantiomerically pure substance (expressed as a percent). Optical purity is numerically equal to enantiomeric excess, but experimentally determined.
An organic compound containing at least one halogen.
A lipid containing glycerol esterifi ed with two molecules of fatty acid and one molecule of phosphoric acid.
For light, the orientation of the electric field.
