In 13C NMR spectroscopy, a technique in which all 13C!1H splitting is suppressed with the use of two rf transmitters.
Chemical shift (d)
The shift in parts per million of an NMR signal relative to the signal of TMS
A model of reaction rates based on the idea that molecules must collide to react; it explains the factors influencing reaction rates in terms of the frequency of collisions, the number of collisions with energies exceeding the activation energy, and the probability that the collisions occur with suitable orientations. (Section 14.5)
A situation in which two multiple bonds are separated by a single bond. Alternatively, a series of overlapping 2p orbitals. 1,3-butadiene, for example, is a conjugated diene, and 3-butene-2-one is a conjugated enone
In electrocyclic reactions,a type of rotation in which the orbitals being used to form the new s bond must rotate in the same way.
critical temperature (Tc).
The temperature above which a gas will not liquefy. (11.8)
Any substituent on a benzene ring that causes the rate of electrophilic aromatic substitution to be lower than that for benzene.
An anion derived by loss of a hydrogen from a carbon alpha to a carbonyl group; the anion of an enol.
An ion formed by the addition of an electron to a hydrogen atom: H-. (Section 7.7)
An effect that explains why alkyl groups stabilize a carbocation.
The SI unit of energy, 1 kg@m2 >s2. A related unit is the calorie: 4.184 J = 1 cal. (Section 5.1)
A compound containing a carbonyl group bonded to two carbons.
nuclear disintegration series
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one; also called a radioactive series. (Section 21.2)
A form of isomerism in which the two forms of a compound (stereoisomers) are nonsuperimposable mirror images. (Section 23.4)
representative (main-group) element
An element from within the s and p blocks of the periodic table (Figure 6.29). (Section 6.9)
A hydrocarbon that contains no p bonds.
An alternative name for an imine
A mixture of substances that has a uniform composition; a homogeneous mixture. (Section 1.2)
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
