An instrument that measures atmospheric pressure. (5.2)
A reactive intermediate formed by b-elimination from adjacent carbon atoms of a benzene ring and having a triple bond in the benzene ring. The second p bond of the benzyne triple bond is formed by the weak overlap of coplanar 2p orbitals on adjacent carbons.
critical pressure (Pc).
The minimum pressure necessary to bring about liquefaction at the critical temperature. (11.8)
Tools that are used for drawing resonance structures and for showing the flow of electron density during each step of a reaction mechanism.
For chair conformations of substituted cyclohexanes, a position that is approximately along the equator of the ring.
A reaction that has a rate equation in which the sum of all exponents is one.
An amorphous solid formed by fusion of SiO2, CaO, and Na2O. Other oxides may also be used to form glasses with differing characteristics. (Section 22.10)
A region of space that can hold two electrons
A C6H5 group.
A carbohydrate containing a large number of monosaccharide units, each joined to the next by one or more glycosidic bonds.
A voltaic cell that cannot be recharged. (Section 20.7)
A crystal lattice in which the lattice points are located only at the corners of each unit cell. (Section 12.2)
retro Diels-Alder reaction
The reverse of a Diels-Alder reaction, achieved at high temperature. A cyclohexene derivative is converted into a diene and a dienophile.
The combination of a Michael addition followed by an aldol condensation to form a ring.
Compounds that have the same constitution but differ in the 3D arrangement of atoms.
Strain that arises when nonbonded atoms separated by three bonds are forced from a staggered conformation to an eclipsed conformation. Torsional strain is also called eclipsed-interaction strain.
A triester formed from glycerol and three long-chain carboxylic acids.
A reaction in which only one species is involved in the rate-determining step
A compound with two oppositely charged atoms adjacent to each other.
A net neutral compound that exhibits charge separation. Amino acids exist as zwitterions at physiological pH.
