Solutions for Chapter 23: Carbohydrates
Full solutions for Organic Chemistry, | 9th Edition
An object that lacks chirality; an object that has no handedness
acid-dissociation constant (Ka)
An equilibrium constant that expresses the extent to which an acid transfers a proton to solvent water. (Section 16.6)
A compound that has the general formula R3N, where R may be H or a hydrocarbon group. (Section 16.7)
A reaction for which the reagent necessary to catalyze the reaction is produced by the reaction itself.
basic oxide (basic anhydride)
An oxide that either reacts with water to form a base or reacts with an acid to form a salt and water. (Section 22.5)
A reactive intermediate formed by b-elimination from adjacent carbon atoms of a benzene ring and having a triple bond in the benzene ring. The second p bond of the benzyne triple bond is formed by the weak overlap of coplanar 2p orbitals on adjacent carbons.
A law stating that at constant pressure, the volume of a given quantity of gas is proportional to absolute temperature. (Section 10.3)
cubic close packing
A crystal structure where the atoms are packed together as close as possible, and the close-packed layers of atoms adopt a three-layer repeating pattern that leads to a face-centered cubic unit cell. (Section 12.3)
Strands of a polymer that are generated when the polymer is heated, forced through small holes, and then cooled.
The energy that an object possesses by virtue of its motion. (Section 5.1)
The vectors a, b, and c that define a crystal lattice. The position of any lattice point in a crystal can be represented by summing integer multiples of the lattice vectors. (Section 12.2)
In NMR spectroscopy, if n is the number of neighboring protons, then the multiplicity will be n+1.
A naturally occurring mixture of gaseous hydrocarbon compounds composed of hydrogen and carbon. (Section 5.8)
Changes (such as a phase change) that occur with no change in chemical composition. (Section 1.3)
A constant of proportionality between the reaction rate and the concentrations of reactants that appear in the rate law. (Section 14.3)
A measure of the decrease in concentration of a reactant or the increase in concentration of a product with time. (Section 14.2)
An applied magnetic fi eld causes the p electrons of an aromatic ring to circulate, giving rise to the so-called ring current and an associated magnetic fi eld that opposes the applied fi eld in the middle of the ring but reinforces the applied fi eld on the outside of the ring.
Atomic orbitals that are achieved by mathematically averaging one s orbital with two p orbitals to form three hybridized atomic orbitals.
The total of (single bonds + lone pairs) for an atom in a compound.
A compound that contains two SR groups, both of which are connected to the same carbon atom.
