A reaction involving the addition of two groups to a conjugated p system in which one group is installed at the C1 position and the other group is installed at the C2 position.
A measure of how closely individual measurements agree with the correct value. (Section 1.5)
A substance that yields hydrogen ions (H1) when dissolved in water. (2.7)
Bond dissociation enthalpy
The amount of energy required to break a bond into two radicals in the gas phase at 25°C, A!B !> A• 1 •B
A type of double-stranded DNA in which the 59 and 39 ends of each strand are joined by phosphodiester groups.
The metal ion and its surrounding ligands. (Section 23.2)
The process in which molecules, ions, or atoms come together to form a crystalline solid. (Section 13.2)
A carbohydrate containing two monosaccharide units joined by a glycosidic bond.
A reaction in which the Gibbs free energy of the products is higher than that of the reactants. The position of equilibrium for an endergonic reaction favors starting materials
levorotatory, or merely levo or l
A term used to label a chiral molecule that rotates the plane of polarization of plane-polarized light to the left (counterclockwise). (Section 24.4)
An assembly of a metal ion and the Lewis bases bonded to it. (Section 23.2)
The concentration of a solution expressed as moles of solute per kilogram of solvent; abbreviated m. (Section 13.4)
Molecules with low molecular weights, which can be joined together (polymerized) to form a polymer. (Section 12.8)
Radiation that does not have sufficient energy to remove an electron from a molecule. (Section 21.9)
polar covalent bond
A bond in which the difference in electronegative values of the two atoms is between 0.5 and 1.7.
A measure of the force exerted on a unit area. In chemistry, pressure is often expressed in units of atmospheres (atm) or torr: 760 torr = 1 atm; in SI units pressure is expressed in pascals (Pa). (Section 10.2)
A characteristic that gives a sample of matter its unique identity. (Section 1.1)
The base-catalyzed hydrolysis of an ester. This method is used to make soap.
The preferred metric units for use in science. (Section 1.4)
