Bordwell pKa Table

pKa is an acid dissociation constant used to describe the acidity of a particular molecule. Its value is directly related to the structure of the given compound. The constant changes depending on the solvent the compound is used in. Typically, organic chemists compare the various values from their determination in water, DMSO and the gas phase and use these to predict a compounds reactivity, solubility, and other physical characteristics. More information on pKa's can be obtained. Bordwell pKa Table (Acidity in DMSO) Organic Chemistry Info. UW Chemistry home. UW Organic Chemistry home. Drawings produced with WINPLT.

An isocyanide is an organic compound with the functional group -N≡C. It is the isomer of the related nitrile, hence the prefix is isocyano. The organic fragment is connected to the isocyanide group through the nitrogen atom, not via the carbon. They are used as building blocks for the synthesis of other compounds Evans pKa table.

Cak Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.. The word surfactant is a blend of surface-active agent, coined c. 1950.. Agents that increase surface tension are surface active in.

Nitromethane, sometimes shortened to just Nitro, is an organic compound with the chemical formula CH 3NO 2. It is the simplest organic nitro compound. It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent. As an intermediate in organic synthesis, it is used widely in the manufacture of pharmaceuticals, pesticides, explosives, fibers, and coatings. Nitromethane is used as a fuel additive in Bordwell pKa Table This page by Professor Hans Reich (UW-Madison) provides a collection of common structural motifs in Organic Chemistry and their corresponding pKa values. www.chem.wisc.ed

Aniline is a clear to slightly yellow liquid with a characteristic odor. It does not readily evaporate at room temperature. Aniline is slightly soluble in water and mixes readily with most organic solvents. Aniline is used to make a wide variety of products such as polyurethane foam, agricultural chemicals, synthetic dyes, antioxidants, stabilizers for the. pKa Table: Bordwell pKa Table (Hans Reich, U.
