A carbon atom that is immediately adjacent to a benzene ring.
An alkane containing two rings that share two carbons
The most common drawing style employed by organic chemists. All carbon atoms and most hydrogen atoms are implied but not explicitly drawn in a bond-line structure.
A substance (molecule or ion) that acts as a proton donor. (Section 16.2)
elimination (of radicals)
In radical reaction mechanisms, a step in which a bond forms between the alpha (a) and beta (b) positions. As a result, a single bond at the b position is cleaved, causing the compound to fragment into two pieces.
A derivative of a carboxylic acid in which H of the carboxyl group is replaced by a carbon.
A higher energy state than the ground state. (Section 6.3)
heat of combustion
The heat given off during a reaction in which an alkane reacts with oxygen to produce CO2 and water.
The relationship among the pH, pKa, and the concentrations of acid and conjugate base in an aqueous solution: pH = pKa + log 3base4 3acid4. (Section 17.2)
Water repelling. The term is often used to describe a type of colloid. (Section 13.6)
An electronwithdrawing group that directs the regiochemistry of an electrophilic aromatic substitution reaction such that the incoming electrophile is installed at the meta position.
The arrangement of elements in order of increasing atomic number, with elements having similar properties placed in vertical columns. (Section 2.5)
A device that measures the rotation of plane-polarized light caused by optically active compounds.
A conformation of a conjugateddiene in which the disposition of the two p bonds with regard to the connecting single bond is translike (a dihedral angle of 180°).
The threedimensional conformations of localized regions of a protein, including helices and b-pleated sheets.
Atomic orbitals that are achieved by mathematically averaging one s orbital with only one p orbital to form two hybridized atomic orbitals.
An atom, most commonly carbon, about which exchange of two groups produces a stereoisomer. Chiral centers are one type of stereocenter
Common leaving groups. Examples include tosylate, mesylate, and triflate ions.
For mechanisms, a step that involves three chemical entities.
A solution to a set of equations that defi nes the energy of an electron in an atom and the region of space it may occupy.
