A group derived by removing a hydrogen from an alkane; given the symbol R!
The average mass of the atoms of an element in atomic mass units (amu); it is numerically equal to the mass in grams of one mole of the element. (Section 2.4)
A polymer that is formed under conditions in which the monomers do not react directly with each other, but rather, each monomer is added to the growing chain, one at a time.
Elimination of water.
Diamagnetic current in NMR
The circulation of electron density in a molecule in an applied magnetic fi eld.
A bimolecular eliminationreaction.eclipsed conformation (Sect. 4.7): A conformationin which groups are eclipsing each other in aNewman projection.
A bond to a chair conformation of cyclohexane that extends from the ring roughly perpendicular to the imaginary axis through the center of the ring; a bond that lies roughly along the equator of a cyclohexane ring
first law of thermodynamics
A statement that energy is conserved in any process. One way to express the law is that the change in internal energy, ?E, of a system in any process is equal to the heat, q, added to the system, plus the work, w, done on the system by its surroundings: ?E = q + w. (Section 5.2)
A barbed curved arrow used to show the change in position of a single electron.
A law stating that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. (Section 10.8)
High-density lipoprotein (HDL)
Plasma particles, density 1.06–1.21 g/mL, consisting of approximately 33% proteins, 30% cholesterol, 29% phospholipids, and 8% triglycerides.
A reaction in which bonds are cleaved by treatment with water.
net ionic equation
A chemical equation for a solution reaction in which soluble strong electrolytes are written as ions and spectator ions are omitted. (Section 4.2)
One of the four arrow-pushing patterns for ionic reactions.
A compound that rotates plane-polarized light.
Addition of a reagent to a metal center causing it to add two substituents and to increase its oxidation state by two
The sign of the wave function at particular coordinates in space, either plus or minus. Phasing is often represented by colors, such as red or blue
The process by which water molecules move under high pressure through a semipermeable membrane from the more concentrated to the less concentrated solution. (Section 18.4)
A term used to indicate that exactly two alkyl groups are attached directly to a particular position. For example, a secondary carbocation has two alkyl groups attached directly to the electrophilic carbon atom (C+).
Exchange of the !OR or !OAr group of an ester for another !OR or !OAr group.
