The product formed when the C"O group of a monosaccharide is reduced to a CHOH group.
An !OR group where R is an alkyl group
One-half the distance between the two nuclei in two adjacent atoms of the same element in a metal. For elements that exist as diatomic units, the atomic radius is one-half the distance between the nuclei of the two atoms in a particular molecule. (8.3)
The most common drawing style employed by organic chemists. All carbon atoms and most hydrogen atoms are implied but not explicitly drawn in a bond-line structure.
A species in which a carbon atom has only six electrons in its valence shell and bears a positive charge
A compound that contains the ¬COOH functional group. (Sections 16.10 and 24.4)
The process by which a metal is oxidized by substances in its environment. (Section 20.8)
The process of preparing a less concentrated solution from a more concentrated one by adding solvent. (Section 4.5)
A mode of radioactive decay in which an inner-shell orbital electron is captured by the nucleus. (Section 21.1)
The ability to do work.
The total energy possessed by a system. When a system undergoes a change, the change in internal energy, ?E, is defined as the heat, q, added to the system, plus the work, w, done on the system by its surroundings: ?E = q + w. (Section 5.2)
A C6H5 group.
Polymers made up of repeating monosaccharide units linked together by glycoside bonds.
Resonance in NMR spectroscopy
The absorption of electromagnetic radiation by a precessing nucleus and the resulting “fl ip” of its nuclear spin from the lower energy state to the higher energy state.
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.
The preferred metric units for use in science. (Section 1.4)
Specifi c rotation
The observed rotation of the plane of polarized light when a sample is placed in a tube 1.0 dm in length and at a concentration of 1 g/mL for a solution. For a pure liquid, concentration is expressed in g/mL (density).
Highly crosslinked polymers that are generally very hard and insoluble.
A nonplanar conformation of a cyclohexane ring that is twisted from and slightly more stable than a boat conformation.
van der Waals forces
A group of intermolecular attractive forces including dipole-dipole, dipole-induced dipole, and induced dipole-induced dipole (dispersion) forces
