Full solutions for Modern Chemistry: Student Edition 2006 | 1st Edition
Polymerization that occurs through coupling of monomers with one another, with no other products formed in the reaction. (Section 12.8)
A group derived by removing a hydrogen from an alkane; given the symbol R!
A solution in which water is the solvent. (Chapter 4: Introduction)
An equation that relates the rate constant for a reaction to the frequency factor, A, the activation energy, Ea, and the temperature, T: k = Ae-Ea>RT. In its logarithmic form it is written ln k = -Ea>RT + ln A. (Section 14.5)
A conformation of cyclohexane in which all bond angles are fairly close to 109.5° and many hydrogen atoms are eclipsing each other.
A law stating that at constant pressure, the volume of a given quantity of gas is proportional to absolute temperature. (Section 10.3)
Properties that describe a substance’s composition and its reactivity; how the substance reacts or changes into other substances. (Section 1.3)
A barbed curved arrow used to show the change in position of a single electron.
An electrophilic aromatic substitution in which a hydrogen of an aromatic ring is replaced by an alkyl or acyl group.
A functional group in which two acyl groups, RCO! or ArCO!, are bonded to a nitrogen atom
The withdrawal of electron density that occurs when a bond is shared by two atoms of differing electronegativity.
A reaction in which an acid and a base react in stoichiometrically equivalent amounts; the neutralization reaction between an acid and a metal hydroxide produces water and a salt. (Section 4.3)
The loss of electrons. Alternatively, either the loss of hydrogens, the gain of oxygens, or both.
A property that a substance possesses if it contains one or more unpaired electrons. A paramagnetic substance is drawn into a magnetic field. (Section 9.8)
A polyester in which the carboxyl groups are derived from carbonic acid
quaternary ammonium salt
An ionic compound containing a positively charged nitrogen atom connected to four alkyl groups.
A compound with a weak bond that undergoes homolytic bond cleavage with great ease, producing radicals that can initiate a radical chain process.
sp3 Hybrid orbital
A hybrid atomic orbital formed by the combination of one s atomic orbital and three 2p atomic orbitals.
A compound containing an SRO bond that is flanked on both sides by R groups.
