Apicophilicity

  "id": "MLC-T-CHM-000732",
  "term": "Apicophilicity",
  "field": "Chemistry",
  "definition": "The preference of a substituent in a trigonal bipyramidal molecule to occupy an apical position rather than an equatorial one. This preference is influenced by factors such as electronegativity and steric bulk of the substituent. More electronegative substituents generally exhibit higher apicophilicity in phosphorus compounds.",
