A conformation about a single bond in which two groups on adjacent carbons lie at a dihedral angle of 180°.
antibonding molecular orbital
A molecular orbital in which electron density is concentrated outside the region between the two nuclei of bonded atoms. Such orbitals, designated as s* or p*, are less stable (of higher energy) than bonding molecular orbitals. (Section 9.7)
An elimination reaction in which a proton from the beta (b) position is removed together with the leaving group, forming a double bond.
A thermodynamic cycle based on Hess’s law that relates the lattice energy of an ionic substance to its enthalpy of formation and to other measurable quantities. (Section 8.2)
A substance capable of accepting a proton. (4.3)
A lipid that readily undergoes hydrolysis in aqueous acid or base to produce smaller fragments.
Atoms that lie in the same plane.
The gradual mixing of molecules of one gas with the molecules of another by virtue of their kinetic properties. (5.7)
Ground-state electron confi guration
The lowest-energy electron confi guration for an atom or molecule.
A homogeneous alloy with definite properties and a fixed composition. Intermetallic compounds are stoichiometric compounds that form between metallic elements. (Section 12.3)
law of mass action
The rules by which the equilibrium constant is expressed in terms of the concentrations of reactants and products, in accordance with the balanced chemical equation for the reaction. (Section 15.2)
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)
In atomic and molecular orbitals, a location where the value of y is zero.
The amide linkage by which two amino acids are coupled together to form peptides.
Planck constant (h)
The constant that relates the energy and frequency of a photon, E = hn. Its value is 6.626 * 10-34 J@s. (Section 6.2)
Any chemical species that contains one or more unpaired electrons.
A solution in which undissolved solute and dissolved solute are in equilibrium. (Section 13.2)
Atomic orbitals that are achieved by mathematically averaging one s orbital with two p orbitals to form three hybridized atomic orbitals.
A reaction for which the ratio of products is determined solely by the distribution of energy among the products.
Electrons in the valence (outermost) shell of an atom.
