Any substituent on a benzene ring that causes the rate of electrophilic aromatic substitution to be greater than that for benzene.
alpha (a) helix
For proteins, a feature of secondary structure that forms when a portion of the protein twists into a spiral.
Compounds containing a nitrogen atom that is connected to one, two, or three alkyl or aryl groups.
Compounds consisting of a single ring containing a fully conjugated p system. Benzene is annulene.
In SN2 reactions, the side opposite the leaving group, which is where the nucleophile attacks.
basic oxide (basic anhydride)
An oxide that either reacts with water to form a base or reacts with an acid to form a salt and water. (Section 22.5)
An electrode at which reduction occurs. (Section 20.3)
conjugate acid–base pair
An acid and a base, such as H2O and OH-, that differ only in the presence or absence of a proton. (Section 16.2)
The separation on an NMR spectrum (in hertz) between adjacent peaks in a multiplet and a quantitative measure of the infl uence of the spin-spin coupling with adjacent nuclei.
A molecule that consists of two atoms. (2.5)
The process of preparing a less concentrated solution from a more concentrated one by adding solvent. (Section 4.5)
A method of problem solving in which units are carried through all calculations. Dimensional analysis ensures that the final answer of a calculation has the desired units. (Section 1.6)
electrospray ionization (ESI):
In mass spectrometry, an ionization technique in which the compound is first dissolved in a solvent and then sprayed via a high-voltage needle into a vacuum chamber. The tiny droplets of solution become charged by the needle, and subsequent evaporation forms gas-phase molecular ions that typically carry one or more charges.
A reaction that occurs between chlorobenzene and either NaOH (at high temperature) or NaNH2.
A cyclic ether in which oxygen is one atom of a three-membered ring
An orbital that results from the mixing of different kinds of atomic orbitals on the same atom. For example, an sp3 hybrid results from the mixing, or hybridizing, of one s orbital and three p orbitals. (Section 9.5)
Solvation when the solvent is water. (Section 13.1)
An allowed energy state of an electron in the quantum mechanical model of the atom; the term orbital is also used to describe the spatial distribution of the electron. An orbital is defined by the values of three quantum numbers: n, l, and ml (Section 6.5)
From the Greek, poly 1 meros, meaning many parts. Any long-chain molecule synthesized by linking together many single parts called monomers
ribonucleic acid (RNA)
A polynucleotide in which ribose is the sugar component. (Section 24.10)
