Full solutions for Organic Chemistry, | 9th Edition
A reaction involving the addition of two groups to a conjugated p system in which one group is installed at the C1 position and the other group is installed at the C2 position.
Carbohydrate derivatives in which an OH group has been replaced with an amino group.
Compounds containing only covalent bonds. (9.4)
Having the same energy.
Diamagnetic current in NMR
The circulation of electron density in a molecule in an applied magnetic fi eld.
A material that, when stretched or otherwise distorted, returns to its original shape when the distorting force is released.
The group that is displaced in a substitution reaction or the Lewis base that is lost in an elimination reaction
Phosphoglycerides thatcontain choline.
A substance that exhibits one or more partially ordered liquid phases above the melting point of the solid form. By contrast, in nonliquid crystalline substances the liquid phase that forms upon melting is completely unordered. (Section 11.7)
A compound that possesses chirality centers and an internal plane of symmetry.
Elements that lie along the diagonal line separating the metals from the nonmetals in the periodic table; the properties of metalloids are intermediate between those of metals and nonmetals. (Section 2.5)
normal melting point
The melting point at 1 atm pressure. (Section 11.6)
Part per million (ppm)
Units used on NMR spectra to record chemical shift relative to the TMS standard.
The breaking of a molecule into two or more neutral fragments as a result of absorption of light. (Section 18.2)
A crystal lattice in which the lattice points are located only at the corners of each unit cell. (Section 12.2)
A process in which heat converts a mineral in an ore from one chemical form to another and eventually to the free metal. (Section 23.2)
reaction quotient (Q)
The value that is obtained when concentrations of reactants and products are inserted into the equilibrium expression. If the concentrations are equilibrium concentrations, Q = K; otherwise, Q ? K. (Section 15.6)
The amount of time required for a compound to exit from a gas chromatograph.
S (Section 3.3
From the Latin, sinister, left; used in the R,S convention to show that the order of priority of groups on a chiral center is counterclockwise
The more substituted product (alkene) of an elimination reaction.
