distinguish between sigma and pie bond

Answer:
Explanation:
Difference Between Sigma and Pi bond
Sigma Bond
Pi Bond
During sigma bond formation overlapping orbitals can be either one hybrid and one pure orbital or two pure orbitals and two hybrid orbitals.
During pi bond formation overlapping orbitals are always two unhybridized orbitals.
Sigma bond exists independently and allows free rotation.
Pi-bond always exists along with sigma bond and the rotation is restricted.
Sigma bonds are stronger bonds.
Pi bonds are usually less powerful compared to sigma bonds.
Sigma bonds are formed first when atoms interact.
Pi bonds are formed after the formation of sigma bonds.
During the bonding between two atoms,
Only one sigma bond is formed.
Here two pi bonds can exist between two atoms.
Sigma bond has cylindrical charge symmetry around the bond axis.
No symmetry exists in pi bonds.
Atoms with sigma bonds can be highly reactive.
Atoms with pi bonds are less reactive in nature.
Sigma bond can be used to determine the shape of a molecule.
Pi bond cannot be used for the same purpose.
Answer:
SIGMA BOND:
A covalent bond formed due to overlap of orbitals of the two atoms along the line joining the two nuclei.
PI BOND:
A covalent bond form due to the sideways overlap of their p orbitals.
