Full solutions for Organic Chemistry | 6th Edition
A format for naming primary amines containing a complex alkyl group.
A three-dimensional plot of y2 of a wavefunction. It is a region of space that can accommodate electron density.
A class of substances formed from polyhydroxy aldehydes or ketones. (Section 24.8)
A polysaccharide of glucose; it is the major structural element in plant matter. (Section 24.8)
A polymer in which neighboring chains are linked together, for example, by disulfide bonds.
Tools that are used for drawing resonance structures and for showing the flow of electron density during each step of a reaction mechanism.
Dalton’s law of partial pressures
A law stating that the total pressure of a mixture of gases is the sum of the pressures that each gas would exert if it were present alone. (Section 10.6)
A model for the behavior of electrons in metals. (Section 12.4)
The expression that describes the relationship among the concentrations (or partial pressures) of the substances present in a system at equilibrium. The numerator is obtained by multiplying the concentrations of the substances on the product side of the equation, each raised to a power equal to its coefficient in the chemical equation. The denominator similarly contains the concentrations of the substances on the reactant side of the equation. (Section 15.2)
For substituted cycloalkanes, a drawing style used to clearly identify which groups are above the ring and which groups are below the ring. (See also Sect. 4.14.)
Hückel criteria for aromaticity
To be aromatic, a monocyclic compound must have one 2p orbital on each atom of the ring, be planar or nearly so, and have (4n 1 2) p electrons in the cyclic arrangement of 2p orbitals
A cyclic amide.
A model of enzyme action in which the substrate molecule is pictured as fitting rather specifically into the active site on the enzyme. It is assumed that in being bound to the active site, the substrate is somehow activated for reaction. (Section 14.7)
A plot of the relative abundance of ions versus their mass-to-charge ratio
root-mean-square (rms) speed 1M2
The square root of the average of the squared speeds of the gas molecules in a gas sample. (Section 10.7)
Matter that has both a definite shape and a definite volume. (Section 1.2)
sp2 Hybrid orbital
A hybrid atomic orbital formed by the combination of one s atomic orbital and two 2p atomic orbitals.
Tertiary (3°) amine
An amine in which nitrogen is bonded to three carbons
An ether(R!O!R) where the two R groups are notidentical.
van der Waals radius
The minimum distance of approach to an atom that does not cause nonbonded interaction strain.
