A form of magnetism in which unpaired electron spins on adjacent sites point in opposite directions and cancel each other’s effects. (Section 23.1)
As protons are added one by one to the nucleus to build up the elements, electrons similarly are added to the atomic orbitals. (7.9)
A compound that contains the ¬COOH functional group. (Sections 16.10 and 24.4)
The lowest energy conformation for cyclohexane, in which all bond angles are fairly close to 109.5° and all hydrogen atoms are staggered.
A complex polymer resulting from the polymerization of two or more chemically different monomers. (Section 12.8)
A cumulated diene is one in which two double bonds share an sp-hybridized carbon
The region of an IR spectrum that contains signals that arise from double bonds, triple bonds, and X!H bonds.
A molecule with one end having a partial negative charge and the other end having a partial positive charge; a polar molecule. (Section 8.4)
Very weak intermolecular forces of attraction resulting from the interaction between temporary induced dipoles
Intermolecular forces resulting from attractions between induced dipoles. Also called London dispersion forces. (Section 11.2)
A process in which a system absorbs heat from its surroundings. (Section 5.2)
Atoms of the same element containing different numbers of neutrons and therefore having different masses. (Section 2.3)
Molecular dipole moment (m)
The vector sum of individual bond dipoles.
Compounds formed when hydrogen reacts with nonmetals and metalloids. (Section 22.2)
In mass spectrometry, an odd molecular weight indicates an odd number of nitrogen atoms in the compound, while an even molecular weight indicates either an even number of nitrogen atoms or the absence of nitrogen.
Cleavage by light.
A polymer that can be molded when hot and retains its shape when cooled
An equation that relates the reaction rate to the concentrations of reactants (and sometimes of products also). (Section 14.3)
