A polymer in which the repeating units contain chirality centers which are not arranged in a pattern (they have random configurations).
A proton acceptor
A species in which a carbon atom has only six electrons in its valence shell and bears a positive charge
A compound containing a carboxyl, !COOH, group.
cholesteric liquid crystalline phase
A liquid crystal formed from flat, disc-shaped molecules that align through a stacking of the molecular discs. (Section 11.7)
dissolving metal reduction
A reaction in which an alkyne is converted into a trans alkene.
The resonance-stabilized conjugate base of a ketone, aldehyde, or ester.
For electromagnetic radiation, the number of wavelengths that pass a particular point in space per unit time.
The energy released when 1 g of a substance is combusted. (Section 5.8)
Two groups connected to the same carbon atom. For example, a geminal dihalide is a compound with two halogens connected to the same carbon atom.
Glass transition temperature (TG)
The temperature at which a polymer undergoes the transition from a hard glass to a rubbery state
Chemistry that promotes the design and application of chemical products and processes that are compatible with human health and that preserve the environment. (Section 18.5)
Atoms or groups on an atom that give an achiral molecule when one of the groups is replaced by another group. The hydrogens of the CH2 group of propane, for example, are homotopic. Replacing either one of them with deuterium gives 2-deuteropropane, which is achiral. Homotopic groups have identical chemical shifts under all conditions
A measure of the amount of material in an object. It measures the resistance of an object to being moved. In SI units, mass is measured in kilograms. (Section 1.4)
A reaction in which a nucleophile attacks a conjugated p system, resulting in a 1,4-addition.
nematic liquid crystalline phase
A liquid crystal in which the molecules are aligned in the same general direction, along their long axes, but in which the ends of the molecules are not aligned. (Section 11.7)
A point in space where the value of a wave function is zero
A lipid containing glycerol esterifi ed with two molecules of fatty acid and one molecule of phosphoric acid.
The stabilization associated with the delocalization of electrons via resonance.
Compounds containing a mercapto group (SH).
