Sigma bonds and pi bonds differ in the pattern that the atomic orbitals overlap in, i.e. pi bonds are formed from sidewise overlapping whereas the overlapping along the axis containing the nuclei of the two atoms leads to the formation of sigma bonds. The formation of sigma and pi bonds is illustrated below. It can be noted that sigma bonds ...The strength of a bond depends on the extent to which the orbitals overlap. The more pronounced the overlapping, the stronger the bond. The overlapping occurs more in sigma bonds than in pi bonds. Hence, sigma bonds are stronger than pi bonds. It is why reactions in organic chemistry mainly involve breaking the pi bond rather than the sigma bonds. Sigma bonds are formed by head-on the overlap of atomic orbitals. Whereas pi bonds are formed in addition to sigma bonds by sideways overlapping of atomic orbitals. Since the information of a sigma bond, the orbitals are along internuclear axis this results in more effective orbital overlap as compared to when pi bonds are formed as they are ...Common sigma bonds are s + s, p z + p z and s + p z, z is the axis of the bond on the xyz-plane of the atom. π bonds are created when there is adequate overlap of similar, adjacent p orbitals, such as p x + p x and p y + p y.
