The increase in energy associated with a bond angle that has deviated from the preferred angle of 109.5°.
The SI unit of radioactivity. It corresponds to one nuclear disintegration per second. (Section 21.4)
The species formed when an acid transfers a proton to a base
A ratio relating the same quantity in two systems of units that is used to convert the units of measurement. (Section 1.6)
A pericyclic process in which a conjugated polyene undergoes cyclization. In the process, one p bond is converted into a s bond, while the remaining p bonds all change their location. The newly formed s bond joins the ends of the original p system,thereby creating a ring.
A mode of radioactive decay in which an inner-shell orbital electron is captured by the nucleus. (Section 21.1)
Atoms or groups on an atom that give a chiral center when one of the groups is replaced by another group. A pair of enantiomers results. The hydrogens of the CH2 group of ethanol, for example, are enantiotopic. Replacing one of them by deuterium gives (R)-1-deuteroethanol; replacing the other gives (S)-1-deuteroethanol. Enantiotopic groups have identical chemical shifts in achiral environments but different chemical shifts in chiral environments.
Coal, oil, and natural gas, which are presently our major sources of energy. (Section 5.8)
A five-membered cyclic hemiacetal form of a carbohydrate.
Different compounds with the same molecular formula.
Structural isomers of coordination compounds in which a ligand differs in its mode of attachment to a metal ion. (Section 23.4)
A combination of two or more substances in which each substance retains its own chemical identity. (Section 1.2)
partially condensed structures
A drawing style in which the CH bonds are not drawn explicitly, but all other bonds are drawn.
A solvent that is a hydrogen-bond donor. Common protic solvents are water, low-molecular-weight alcohols, and low-molecular weight carboxylic acids.
An isotope that is radioactive; that is, it is undergoing nuclear changes with emission of radiation. (Section 21.1)
A process of reasoning backwards from a target molecule to a suitable set of starting materials.
Secondary structure of proteins
The ordered arrangements (conformations) of amino acids in localized regions of a polypeptide or protein
A term used to indicate that a certain volume of a compound will dissolve in a specified amount of a liquid at room temperature.
Lipids that are based on a tetracyclic ring system involving three six-membered rings and one five-membered ring. Cholesterol is an example.
An element, such as carbon, that forms four bonds.
