Difference between Sigma and Pi Bond: The following are the points of difference between Sigma and Pi Bond. Sigma Bond Pi Bond This bond is formed by the overlap of orbitals along their internuclear axis (end to end overlap). This is formed by sideway overlapping of orbitals (lateral overlapping). This bond is formed by overlapping between S-S, S-P or P-P orbitals. This bond is formed by the overlap of P-P orbitals only. Overlapping is quite large and hence Sigma bond is a strong bond. Overlapping is to a small extent. Hence Pi bond is a weak bond. There is a … Continue reading Difference between Sigma and Pi Bond
