Consider the following statements.  I. Pi-Bond is stronger than the Sigma Bond.  II. Sigma Bond is formed by linear overlapping of atomic orbitals.  III. In the case of Pi-Bond, the extent of overlapping of atomic orbitals is more as compared to the Sigma Bond.  Which among the above is/are NOT correct? Correct Answer Both I and III 

  • Sigma Bond is formed by linear overlapping of atomic orbitals and that is why the extent of overlapping is more in this type of bond. 
  • Pi-Bond is formed by lateral overlapping of atomic orbitals and that is why the extent of overlapping is lesser as compared to the Sigma Bonds. 
  • Sigma Bond is a stronger bond as compared to the Pi-Bond. 
  • Sigma Bonds are generally recognized by the single lines in a molecule whereas, for Pi-Bonds, there are double lines. 
  • For Example, if we take CH3 - CH= CH2, there are 8 sigma bonds and 1 pi-bond.
