Solutions for Chapter 2.3: Using Scientific Measurements
Full solutions for Modern Chemistry: Student Edition 2012 | 1st Edition
Elements that have incompletely filled 5f subshells or readily give rise to cations that have incompletely filled 5f subshells. (7.9)
A polymerization that involves sequential addition reactions, either to unsaturated monomers or to monomers possessing other reactive functional groups.
Polymerization in which molecules are joined together through condensation reactions. (Section 12.8)
A procedure for preparing a less concentrated solution from a more concentrated solution. (4.5)
The left side of an NMR spectrum.
electrostatic potential maps
A three-dimensional, rainbowlike image used to visualize partial charges in a compound.
energy of activation
In an energy diagram, the height of the energy barrier (the hump) between the reactants and the products.
A form of magnetism in which unpaired electron spins align parallel to one another. (Section 23.1)
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 ion formed by the addition of an electron to a hydrogen atom: H-. (Section 7.7)
A compound containing two carbon-carbon p bonds that are separated by two or more s bonds.
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)
molecular orbital (MO)
An allowed state for an electron in a molecule. According to molecular-orbital theory, a molecular orbital is entirely analogous to an atomic orbital, which is an allowed state for an electron in an atom. Most bonding molecular orbitals can be classified as s or p, depending on the disposition of electron density with respect to the internuclear axis. (Section 9.7)
The change in specifi c rotation that occurs when an a or b hemiacetal form of a carbohydrate in aqueous solution is converted to an equilibrium mixture of the two forms.
In NMR spectroscopy, a technique in which only the one-bond couplings are observed. CH3 groups appear as quartets, CH2 groups appear as triplets, CH groups appear as doublets, and quaternary carbon atoms appear as singlets.
A material that can be formed into particular shapes by application of heat and pressure. (Section 12.8)
The ease with which the electron cloud of an atom or a molecule is distorted by an outside influence, thereby inducing a dipole moment. (Section 11.2)
A high-energy species formed between two successive reaction steps, that lies in an energy minimum between the two transition states
Polymers that are formed under conditions in which the individual monomers react with each other to form oligomers, which are then joined together to form polymers.
Compounds with the following structure: R!C#C!H
