Why are sigma bond is stronger than pi bond? |
| Answer» The strength of a bond depends on upon the extent of overlapping. A sigma bond stronger than a pi bond. The reason behind this is the orientation of the overlapped orbitals. Sigma bonds result from head-on(co-axial) overlapping while pi bonds are the outcome of lateral(para-axial) overlapping.\xa0The greater the extent of overlapping, the higher the probability of finding the valence electrons in between the nuclei and hence the bond will be stronger.<br>Because in sigma bond overlapping is quite large as compaired to pi bond | |
