Solutions for Chapter Chapter 19: Measuring Energy
Full solutions for Living by Chemistry | 2nd Edition
The binding of molecules to a surface. (Section 14.7)
atomic mass unit (amu)
A unit based on the value of exactly 12 amu for the mass of the isotope of carbon that has six protons and six neutrons in the nucleus. (Sections 2.3 and 3.3)
Bond dipole moment
A measure of the polarity of a covalent bond. The product of the charge on either atom of a polar bond times the distance between the atoms
The rules used in naming substances. (Section 2.8)
A technique by which compounds are separated from each other based on a difference in the way they interact with the medium (the adsorbent) through which they are passed.
conservation of orbital symmetry
During a reaction, the requirement that the phases of the frontier MOs must be aligned.
A covalent bond involving two electron pairs. (Section 8.3)
Polymers that return to their original shape after being stretched.
A graphic method for determining the relative energies of p MOs for planar, fully conjugated, monocyclic compounds.
Members of group 7A in the periodic table. (Section 7.8)
When orbitals of equal energy are available but there are not enough electrons to fi ll all of them completely, one electron is put in each before a second electron is added to any
A reaction in which a proton and a hydroxyl group (OH) are added across a p bond.
Water repelling. The term is often used to describe a type of colloid. (Section 13.6)
A bond between oppositely charged ions. The ions are formed from atoms by transfer of one or more electrons. (Section 8.1)
Experimental conditions under which the composition of the product mixture is determined by the relative rates of formation of each product.
nucleophilic aromatic substitution
A substitution reaction in which an aromatic ring is attacked by a nucleophile, which replaces a leaving group.
A solution containing just one enantiomer, but not its mirror image.
Planck constant (h)
The constant that relates the energy and frequency of a photon, E = hn. Its value is 6.626 * 10-34 J@s. (Section 6.2)
Primary (1°) amine
An amine in which nitrogen is bonded to one carbon and two hydrogens
A method for preparing substituted amines by treating an aldehyde or ketone with an amine in the presence of a reducing agent
