Any reaction in which an atom or group of atoms is substituted for another atom or group of atoms at an allylic carbon.
Antibonding molecular orbital
A molecular orbital in which electrons have a higher energy than they would in isolated atomic orbitals
The electrode at which reduction occurs. (18.2)
Substance capable of conducting electric current. (21.3)
The metal ion and its surrounding ligands. (Section 23.2)
The mass of a substance divided by its volume. (1.6)
A reaction characterized by the addition of two hydroxyl groups (OH) across an alkene.
A reaction in which an element reacts with a compound, displacing an element from it. (Section 4.4)
A cyclic ether in which oxygen is one atom of a three-membered ring
A long, unbranched-chain carboxylic acid, most commonly of 12 to 20 carbons, derived from the hydrolysis of animal fats, vegetable oils, or the phospholipids of biological membranes.
The relationship among the pH, pKa, and the concentrations of acid and conjugate base in an aqueous solution: pH = pKa + log 3base4 3acid4. (Section 17.2)
Infrared (IR) spectroscopy
A spectroscopic technique in which a compound is irradiated with infrared radiation, absorption of which causes covalent bonds to change from a lower vibration state to a higher one. Infrared spectroscopy is particularly valuable for determining the kinds of functional groups present in a molecule.
Molecular dipole moment (m)
The vector sum of individual bond dipoles.
Compounds formed when hydrogen reacts with nonmetals and metalloids. (Section 22.2)
Pauli exclusion principle
No more than two electrons may be present in an orbital. If two electrons are present, their spins must be paired
The branch of science that studies the interaction of matter and radiation.
The conversion of an aryl diazonium salt into fluorobenzene upon treatment with fluoroboric acid (HBF4).
A phenomenon observed most commonly for nonequivalent protons connected to adjacent carbon atoms, in which the multiplicity of each signal is affected by the other.
The right side of an NMRspectrum.
A carbocation in which the positive charge is on one of the carbons of a carbon-carbon double bond.
