The addition of atoms or groups of atoms to opposite faces of a carbon-carbon double bond.
A group that can be readily installed and uninstalled. Used for regiochemical control during synthesis.
A material that can undergo a substantial change in shape via stretching, bending, or compression and return to its original shape upon release of the distorting force. (Section 12.6)
Light and other forms of radiant energy.
frequency factor (A)
A term in the Arrhenius equation that is related to the frequency of collision and the probability that the collisions are favorably oriented for reaction. (Section 14.5)
For a peptide chain,the end that contains the amino group.
normal melting point
The melting point at 1 atm pressure. (Section 11.6)
When used in the context of fats and oils, a mixture of triglycerides that is liquid at room temperature
Order of precedence of functions
A ranking of functional groups in order of priority for the purposes of IUPAC nomenclature.
A nuclear decay process where a positron, a particle with the same mass as an electron but with a positive charge, symbol 0+1e, or b+ is emitted from the nucleus. (Section 21.1)
A characteristic that gives a sample of matter its unique identity. (Section 1.1)
The structure of a protein resulting from the clustering of several individual protein chains into a final specific shape. (Section 24.7)
A compound such as a phenol that selectively reacts with radicals to remove them from a chain reaction and terminate the chain
radioactive decay chain
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one. Also called nuclear disintegration series. (Section 21.2)
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.
A conformational change in which one chair conformation is converted into the other.
A synthetictechnique for preparing racemic a-amino acidsfrom aldehydes.
Strain that arises when nonbonded atoms separated by three bonds are forced from a staggered conformation to an eclipsed conformation. Torsional strain is also called eclipsed-interaction strain.
Z (Section 5.2C)
From the German, zusammen, meaning opposite. Specifi es that groups of higher priority on the carbons of a double bond are on the same side
