A monocyclic compound that is planar or nearly so, has one 2p orbital on each atom of the ring, and has 4n p electrons in the cyclic arrangement of overlapping 2p orbitals, where n is an integer. Antiaromatic compounds are especially unstable
A bond to a chair conformation of cyclohexane that extends from the ring parallel to the imaginary axis through the center of the ring; a bond that lies roughly perpendicular to the equator of the ring.
For mechanisms, a step that involves two chemical entities.
A polymer,that is formed via a condensation reaction.
The highest temperature at which it is possible to convert the gaseous form of a substance to a liquid. The critical temperature increases with an increase in the magnitude of intermolecular forces. (Section 11.4)
A system to specify the confi guration of groups about a carbon-carbon double bond
Light and other forms of radiant energy.
Energy added or released when an electron is added to an atom or molecule.
The three- dimensional arrangement of the electron domains around an atom according to the VSEPR model. (Section 9.2)
An !OH group
Compounds formed between two different halogen elements. Examples include IBr and BrF3. (Section 22.4)
Refers to a substance that rotates the plane of polarized light to the left.
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)
In nomenclature, a numberused to identify the location of a substituent.
A substance capable of dissociating more than one proton in water; H2SO4 is an example. (Section 16.6)
A group that is used during synthesis to protect a functional group from the reaction conditions.
A radioisotope that can be used to trace the path of an element in a chemical system. (Section 21.5)
A vibrational molecular spectroscopy that is complementary to infrared (IR) spectroscopy in that infrared inactive vibrations are seen in Raman spectroscopy.
Secondary (2°) amine
An amine in which nitrogen is bonded to two carbons and one hydrogen
tertiary alkyl halide
An organohalide in which the alpha (a) position is connected to three alkyl groups.
