What are the main postulates of VSEPR theory (Valence Shell Electron Pair Repulsion)?​

Answer»

ANSWER:

The main postulates of VSEPR theory are....

  • The shape of molecule depends on the number of valence shell electron pair around Central atom.
  • The pair of electron in the valence shell repel each other since then their electron clouds are NEGATIVELY charged.
  • These pair of electron are tend to occupy such position in SPACE so that there will be minimum REPULSION and thus maximum distance between them makes the molecule more stable.
  • A multiple bond is treated as single electron pair.
