Differentiate Sigma and pi bond
Dear Student,
Difference between a sigma and a pi bond.-
| Sigma (σ) Bond | Pi (π) Bond |
| (a) the bond is formed by the axial overlap of the atomic orbitals | The bond is formed by the sidewise overlap of atomic orbitals. |
| (b) the overlap is large & a strong bond is formed | The overlap is small & weak bond is formed |
| (c) The electron cloud is symmetrical about the internuclear axis | The electron cloud is unsymmetrical. |
| (d ) all the s orbitals & only one lobe of p orbital is involved in overlapping | S orbital doesn't take part in bond formation, while both lobes of p orbital take part in overlapping |
| (e) the bond can also be formed in the absence of pie bond. | The bond cannot be formed in the absence of sigma bond. |
