Oxyanions

Oxyanion

An oxyanion, or oxoanion, is an ion with the generic formula AxOz−y (where A represents a chemical element and O represents an oxygen atom). Oxyanions are formed by a large majority of the chemical elements. The formulae of simple oxyanions are determined by the octet rule. The corresponding oxyacid of an oxyanion is the compound HzAxOy. The structures of condensed oxyanions can be rationalized in terms of AOn polyhedral units with sharing of corners or edges between polyhedra. The oxyanions (specifically, phosphate and polyphosphate esters) adenosine monophosphate (AMP), adenosine diphosphate (ADP) and adenosine triphosphate (ATP) are important in biology. (Wikipedia).

Oxymercuration-Demercuration

We know how to do acid-catalyzed hydration, which is a Markovnikov hydration, but there is another way to do this, one that does not result in carbocation rearrangement. Let's look at the mechanism and application of oxymercuration-demercuration. Watch the whole Organic Chemistry playlist
