POkaksoissidos
POkaksoissidos, in Finnish chemistry terminology P–O kaksoissidos, refers to a phosphorus–oxygen double bond. This bond is a defining feature of many phosphorus–oxygen compounds and is central to the concept of the phosphoryl group (P=O).
Bonding and structure: The P=O bond is highly polar, with substantial electron density drawn toward the oxygen
Occurrence: P=O bonds occur in a range of inorganic and organophosphorus compounds. Classic examples include phosphoryl
Importance and applications: The phosphoryl (P=O) group is a key functional motif in synthesis and materials
