Steric effect

  "id": "MLC-T-CHM-011391",
  "term": "Steric effect",
  "field": "Chemistry",
  "definition": "The influence on a molecule's properties or reactivity arising from the spatial arrangement and size of its atoms or groups. These effects result from repulsive forces between electron clouds of non-bonded atoms when they are brought too close together. Steric hindrance is a common manifestation of a steric effect.",
