Full solutions for Organic Chemistry, | 9th Edition
acidic oxide (acidic anhydride)
An oxide that either reacts with a base to form a salt or with water to form an acid. (Section 22.5)
The energy gap between a fully occupied band called a valence band and an empty band called the conduction band. (Section 12.7)
In a Lewis structure a pair of electrons that is shared by two atoms. (Section 9.2)
A polymer that contains a large number of branches connected to the main chain of the polymer.
In an acid-base reaction, the product that results when a base is protonated.
The process of forming a diazonium salt by treating a primary amine with NaNO2 and HCl.
A form of magnetism in which unpaired electron spins align parallel to one another. (Section 23.1)
In mass spectrometry, when the molecular ion breaks apart into fragments.
An electrophilic aromatic substitution reaction that installs an alkyl group on an aromatic ring.
A complex whose electrons populate the d orbitals to give the maximum number of unpaired electrons. (Section 23.6)
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 nonpolar group that does not have favorable interactions with water.
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.
When used in the context of fats and oils, a mixture of triglycerides that is liquid at room temperature
On an aromatic ring, the C2 position.
A naturally occurring combustible liquid composed of hundreds of hydrocarbons and other organic compounds. (Section 5.8)
Light oscillating in only parallel planes.
A mixture of equal amounts of two enantiomers.
A law stating that the partial pressure of a solvent over a solution, Psolution, is given by the vapor pressure of the pure solvent, P° solvent, times the mole fraction of a solvent in the solution, Xsolvent: Psolution = XsolventP° solvent. (Section 13.5)
A polymer with alternating R and S confi gurations at the chiral centers along its chain, as, for example, syndiotactic polypropylene
