A molecule containing two !OR or !OAr groups bonded to the same carbon
The process of introducing an acyl group, RCO! or ArCO!, onto an organic molecule.
A term used initially to classify benzene and its derivatives. More accurately, it is used to classify any compound that meets the Hückel criteria for aromaticity (Section 21.2A).
A unit of pressure equal to 760 torr; 1 atm = 101.325 kPa. (Section 10.2) atom The smallest representative particle of an element. (Sections 1.1 and 2.1)
axis of symmetry
An axis about which a compound possesses rotational symmetry.
A unit of pressure equal to 105 Pa. (Section 10.2)
An imaginary network of points on which the repeating motif of a solid may be imagined to be laid down so that the structure of the crystal is obtained. The motif may be a single atom or a group of atoms. Each lattice point represents an identical environment in the crystal. (Section 12.2)
A compound containing two adjacent p bonds.
Proteins that consist of chains that are coiled into compact shapes.
Gases in an atmosphere that absorb and emit infrared radiation (radiant heat), “trapping” heat in the atmosphere. (Section 18.2)
The intermediateformed during oxymercuration.
On an aromatic ring, the C4position.
A large molecule of high molecular mass, formed by the joining together, or polymerization, of a large number of molecules of low molecular mass. The individual molecules forming the polymer are called monomers. (Sections 12.1 and 12.8)
A substance made up of many monosaccharide units joined together. (Section 24.8)
Primary structure of nucleic acids
The sequence of bases along the pentose-phosphodiester backbone of a DNA or RNA molecule read from the 5’ end to the 3’ end
A chemical entity with an unpaired electron.
One of the four arrow-pushing patterns for ionic reactions.
The strain that arises when nonbonded atoms separated by four or more bonds are forced closer to each other than their atomic (contact) radii would allow. Steric strain is also called non-bonded interaction strain, or van der Waals strain.
A protein used to transport molecules or ions from one location to another. Hemoglobin is a classic example of a transport protein, used to transport molecular oxygen from the lungs to all the tissues of the body.
A neutral molecule with positive and negative charges on adjacent atoms
