Key Chemistry Terms and definitions covered in this textbook
-
acidic oxide (acidic anhydride)
An oxide that either reacts with a base to form a salt or with water to form an acid. (Section 22.5)
-
alkoxy substituent
An OR group.
-
atom.
The basic unit of an element that can enter into chemical combination. (2.2)
-
atomic number (Z).
The number of protons in the nucleus of an atom. (2.3)
-
autocatalytic
A reaction for which the reagent necessary to catalyze the reaction is produced by the reaction itself.
-
battery
A self-contained electrochemical power source that contains one or more voltaic cells. (Section 20.7)
-
buffer capacity
The amount of acid or base a buffer can neutralize before the pH begins to change appreciably. (Section 17.2)
-
cell potential
The potential difference between the cathode and anode in an electrochemical cell; it is measured in volts: 1 V = 1 J>C. Also called electromotive force. (Section 20.4)
-
Crown ether
A cyclic polyether derived from ethylene glycol and substituted ethylene glycols.
-
density.
The mass of a substance divided by its volume. (1.6)
-
gas
Matter that has no fixed volume or shape; it conforms to the volume and shape of its container. (Section 1.2)
-
labile
Protons that are exchanged at a rapid rate.
-
Lactone
A cyclic ester.
-
living polymer
A polymer that isformed via anionic polymerization.
-
nitrogen rule
In mass spectrometry, an odd molecular weight indicates an odd number of nitrogen atoms in the compound, while an even molecular weight indicates either an even number of nitrogen atoms or the absence of nitrogen.
-
Ostwald process
An industrial process used to make nitric acid from ammonia. The NH3 is catalytically oxidized by O2 to form NO; NO in air is oxidized to NO2; HNO3 is formed in a disproportionation reaction when NO2 dissolves in water. (Section 22.7)
-
overlap
The extent to which atomic orbitals on different atoms share the same region of space. When the overlap between two orbitals is large, a strong bond may be formed. (Section 9.4)
-
proton
A positively charged subatomic particle found in the nucleus of an atom. (Section 2.3)
-
quartet
In NMR spectroscopy, a signal that is comprised of four peaks.
-
spin-pairing energy
The energy required to pair an electron with another electron occupying an orbital. (Section 23.6)
