Regioselectivity

  "id": "MLC-T-CHM-010106",
  "term": "Regioselectivity",
  "field": "Chemistry",
  "definition": "The preference for bond making or breaking at one specific site over other possible sites in a molecule during a chemical reaction. This leads to the preferential formation of one constitutional isomer over others. Markovnikov's rule is a classic example of regioselectivity in addition reactions to alkenes.",
