Physical organic chemistry

allylic substitution reaction

Chemistry; Physical organic chemistry

A substitution reaction occurring at position 1/ of an allylic system, the double bond being between positions 2/ and 3/. The incoming group may be attached to the same atom 1/ as the leaving group, ...

amphiphilic

Chemistry; Physical organic chemistry

A compound containing a large organic cation or anion which possesses a long unbranched hydrocarbon chain, e.g. H 3 C(CH 2 ) n CO 2 - M + H 3 C(CH 2 ) n SO 3 - M + H 3 C(CH 2 ) n N(CH 3 ) 3 + ...

amphiprotic (solvent)

Chemistry; Physical organic chemistry

Self-ionizing solvent possessing both characteristics of Brønsted acids and bases, for example H 2 O and CH 3 OH, in contrast to aprotic solvent.

amphoteric

Chemistry; Physical organic chemistry

A chemical species that behaves both as an acid and as a base is called amphoteric. This property depends upon the medium in which the species is investigated: H 2 SO 4 is an acid when studied in ...

anionotropic rearrangement

Chemistry; Physical organic chemistry

A rearrangement in which the migrating group moves with its electron pair from one atom to another.

annelation

Chemistry; Physical organic chemistry

Alternative, but less desirable term for annulation. The term is widely used in German and French language.

annulation

Chemistry; Physical organic chemistry

A transformation involving fusion of a new ring to a molecule via two new bonds. Some authors use the term "annelation" for the fusion of an additional ring to an already existing one, and ...
