acidic anhydride (acidic oxide)
An oxide that forms an acid when added to water; soluble nonmetal oxides are acidic anhydrides. (Section 22.5)
Hormones that are secreted by the cortex (the outer layer) of the adrenal glands. Adrenocortical hormones are typically characterized by a carbonyl group or hydroxyl group at C11 of the steroid skeleton.
The product obtained when the aldehyde group of an aldose is reduced.
A compound that possesses a carbon-carbon double bond.
A group derived by removing a hydrogen from an alkane; given the symbol R!
A compound containing a planar ring of continuously overlapping p orbitals with 4n+2p electrons.
A state in which the rates of the forward and reverse reactions are equal. (14.1)
cholesteric liquid crystalline phase
A liquid crystal formed from flat, disc-shaped molecules that align through a stacking of the molecular discs. (Section 11.7)
Reactions in which two p systems are joined together in a way that forms a ring. In the process, two p bonds are converted into two s bonds.
The circulation of electron density in the presence of an external magnetic field, which produces a local (induced) magnetic field that opposes the external magnetic field.
A method for analyzing the sequence of amino acids in apeptide by removing one amino acid residue at a time and identifying each residue as it is removed.
A curved arrow with only one barb, indicating the motion of just one electron (also see Sect. 11.1).
A compound containing a carbonyl group bonded to two carbons.
Anything that occupies space and has mass; the physical material of the universe. (Section 1.1)
mean free path
The average distance traveled by a gas molecule between collisions. (Section 10.8)
A way to view a molecule by looking along a carbon-carbon single bond
A starting substance in a chemical reaction; it appears to the left of the arrow in a chemical equation. (Section 3.1)
S (Section 3.3
From the Latin, sinister, left; used in the R,S convention to show that the order of priority of groups on a chiral center is counterclockwise
The study of the energy of chemical structures.
Groups that weakly activate an aromatic ring toward electrophilic aromatic substitution, thereby enhancing the rate of the reaction.
