Question

difference Between Sigma and pi bond

Answer 1

sigma bond > 1>end to end over lapping
2> sigma bond stronger than pi bond
3> sigma bond formed by hybrid orbital

pi bond>1>side wise over lapping
2> pi bond formed by unhybrid orbital

Answer 2

Answer:

Sigma Bond:

• This bond is formed by lateral overlap of atomic orbitals.  
• This bond is formed by the overlap of s–s,s–p or p–p orbitals.
• This bond is stronger because of larger extent of overlapping.
• There can be free rotation of atoms around s bond.
• This bond may be present alone or with a pi bond.

Pi Bond:

• This bond is formed by sideways overlap of atomic orbitals.
• This bond is formed by the overlap of p orbitals. Sometimes d orbitals may also participate in pi bonding.
• This bond is weaker because of lesser extent of overlapping.
• Free rotation of atoms around p bond is not possible.
• This bond is always present with a sigma bond.
