Compounds containing a nitrogen atom that is connected to one, two, or three alkyl or aryl groups.
amino acid residue
The individual repeating units in a polypeptide chain or protein.
A common non-SI unit of length, denoted Å, that is used to measure atomic dimensions: 1Å = 10-10 m. (Section 2.3)
A polymer containing two or more different monomers. (25.2)
Nonequivalent protons for which the replacement test produces diastereomers.
An eliminationreaction in which the leaving group only leavesafter deprotonation occurs. This process occurs atthe end of an aldol condensation.
The capacity to do work or to transfer heat. (Section 5.1)
The energy released when 1 g of a substance is combusted. (Section 5.8)
An amorphous solid formed by fusion of SiO2, CaO, and Na2O. Other oxides may also be used to form glasses with differing characteristics. (Section 22.10)
An equation of state for gases that embodies Boyle’s law, Charles’s law, and Avogadro’s hypothesis in the form PV = nRT. (Section 10.4)
Any molecular vibration that leads to a substantial change in dipole moment and is observed in an IR spectrum.
The arrangement in space of the atoms of a molecule. (Section 9.2)

One of the four arrow-pushing patterns for ionic reactions.
the number of degrees through which a compound rotates the plane of polarized light
A rule stating that bonded atoms tend to possess or share a total of eight valence-shell electrons. (Section 8.1)
A term used to describe the character of a chemical entity (molecule, ion, or radical) exhibiting more than one significant resonance structure.
retro Diels-Alder reaction
The reverse of a Diels-Alder reaction, achieved at high temperature. A cyclohexene derivative is converted into a diene and a dienophile.
A unimolecular nucleophilic substitution reaction.
