For a substituted aromatic ring, the effect of an electron-donating substituent that increases the rate of electrophilic aromatic substitution.
An organic compound containing the hydroxyl group —OH. (24.4)
The product formed when the C"O group of a monosaccharide is reduced to a CHOH group.
base-dissociation constant (Kb)
An equilibrium constant that expresses the extent to which a base reacts with solvent water, accepting a proton and forming OH-1aq2. (Section 16.7)
A positively charged, bridged intermediate formed during the addition reaction that occurs when an alkene is treated with molecular bromine (Br2).
A type of double-stranded DNA in which the 59 and 39 ends of each strand are joined by phosphodiester groups.
Vibrations in the region 1500 to 400 cm21 of an IR spectrum are complex and diffi cult to analyze but are characteristic for different molecules.
A reaction in which an amino group is treated with excess methyl iodide, thereby converting it into an excellent leaving group, followed by treatment with a strong base to give an E2 reaction that yields an alkene.
An OH group.
Atoms of the same element containing different numbers of neutrons and therefore having different masses. (Section 2.3)
A reaction in which a nucleophile attacks a conjugated p system, resulting in a 1,4-addition.
A drawing style that is designed to show the conformation of a molecule.
A system for naming organic compounds.
normal melting point
The melting point at 1 atm pressure. (Section 11.6)
A compound that does not rotate plane-polarized light.
A lipid containing glycerol esterifi ed with two molecules of fatty acid and one molecule of phosphoric acid.
A triglyceride having several carbon-carbon double bonds in the hydrocarbon chains of its three fatty acids.
