-
alkoxy substituent
An OR group.
-
alpha (a) anomer
The cyclic hemiacetal of an aldose in which the hydroxyl group at the anomeric position is trans to the CH2OH
-
anomers
Stereoisomeric cyclic hemiacetals of an aldose or ketose that differ from each other in their configuration at the anomeric carbon.
-
Azeotrope
A liquid mixture of constant composition with a boiling point that is different from that of any of its components.
-
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)
-
boiling-point elevation (DTb).
The boiling point of the solution (Tb) minus the boiling point of the pure solvent (T° b). (12.6)
-
calorimetry.
The measurement of heat changes. (6.5)
-
carbonyl group
The C “O double bond, a characteristic feature of several organic functional groups, such as ketones and aldehydes. (Section 24.4)
-
crown ether
Cyclic polyethers whose molecular models resemble crowns.
-
dehydration
An elimination reaction involving the loss of H and OH.
-
electromotive force (emf)
A measure of the driving force, or electrical pressure, for the completion of an electrochemical reaction. Electromotive force is measured in volts: 1 V = 1 J>C. Also called the cell potential. (Section 20.4)
-
Excited state
A state of a system at higher energy than the ground state.
-
free induction decay
In NMR spectroscopy, a complex signal which is a combination of all of the electrical impulses generated by each type of proton.
-
fuel cell
A voltaic cell that utilizes the oxidation of a conventional fuel, such as H2 or CH4, in the cell reaction. (Section 20.7)
-
Hammond postulate
In an exothermic process the transition state is closer in energy to the reactants than to the products, and therefore the structure of the transition state more closely resembles the reactants. In contrast, the transition state in an endothermic process is closer in energy to the products, and therefore the transition state more closely resembles the products.
-
initiation
In radical reaction mechanisms, a step in which radicals are created.
-
metal complex
An assembly of a metal ion and the Lewis bases bonded to it. (Section 23.2)
-
polarizability
The ability of an atom or molecule to distribute its electron density unevenly in response to external influences.
-
protium
The most common isotope of hydrogen. (Section 22.2)
-
staggered conformation
A conformation in which nearby groups in a Newman projection have a dihedral angle of 60°.
