Himal Rimal asked a question

Sigma bond is stronger than Pi bond because of the following reasons:

  1. The extent of overlapping in Sigma bond is greater than in Pi bond.
  2. The electron density in intermolecular axis is more in Sigma bond than in Pi bond.
  3. There is free rotation of atom about Sigma bond but not about Pi bond.
