A summary of the results of many possible displacement reactions. (4.4)
A positively charged, bridged intermediate formed during the addition reaction that occurs when an alkene is treated with molecular bromine (Br2).
Center of symmetry
A point so situated that identical components of an object are located on opposite sides and equidistant from that point along any axis passing through it.
The metal ion and its surrounding ligands. (Section 23.2)
Atoms or groups on an atom that are bonded to an atom that is bonded to two nonidentical groups, one of which contains a chiral center. When one of the atoms or groups is replaced by another group, a new chiral center is created and a set of diastereomers results. The hydrogens of the CH2 group of 2-butanol, for example, are diastereotopic. Diastereotopic groups have different chemical shifts under all conditions
The atom of a ligand that bonds to the metal. (Section 23.2)
electrophilic aromatic substitution
A substitution reaction in which an aromatic proton is replaced by an electrophile and the aromatic moiety is preserved.
A compound containing a hydroxyl group bonded to a doubly bonded carbon atom.
A drawing style that is often used when dealing with compounds bearing multiple chirality centers, especially for carbohydrates. (See also Sect. 5.7.)
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.)
Compounds composed of only carbon and hydrogen. (Section 2.9)
In 1H NMR spectroscopy, the area under a signal indicates the number of protons giving rise to the signal.
A series of atoms, ions, or molecules having the same number of electrons. (Section 7.3)
A cyclic amide.
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)
The conversion of a substance from one state of matter to another. The phase changes we consider are melting and freezing 1solid ? liquid2, sublimation and deposition, and vaporization and condensation 1liquid ? gas2. (Section 11.4)
redox (oxidation–reduction) reaction
A reaction in which certain atoms undergo changes in oxidation states. The substance increasing in oxidation state is oxidized; the substance decreasing in oxidation state is reduced. (Section 4.4; Chapter 20: Introduction)
sp2 Hybrid orbital
A hybrid atomic orbital formed by the combination of one s atomic orbital and two 2p atomic orbitals.
In IR spectroscopy, atype of vibration that generally produces a signal in the diagnostic region of an IR spectrum.
Constitutional isomers in equilibrium with each other that differ in the location of a hydrogen atom and a double bond relative to a heteroatom, most commonly O, N, or S.
