Question

Sigma bonds are stronger than pie bonds. But why the bond energy of sigma bonds are lesser than that of pie bonds?

Answer 1

Answer:

In sigma bond linear overlapping occurs while in pi bond parallel overlapping occurs.

Explanation:

in sigma bond the bonding occurs by the linear overlap of the orbitals whereas in the pi bond parallel overlapping occurs.

Electron density is maximum between the nuclei of bonded atoms in sigma bond as compared to the pi bond.

Answer 2

Pi bonds are usually weaker than sigma bonds.because the orbital paths are parallel so there is much less o In a pi bond the p orbitals overlap above and below the atom, localizing the electrons above and below the plane of the bond—a higher energy state compared to the head-on overlap of a sigma bond.overlap between the p-orbitals.
