WebAnswer: In pi bonds, there is less overlap than in sigma bonds due to lateral overlap. Sigma bonds are therefore more powerful than pi bonds due to more close contact and greater extent of overlapping. Note that bond length affects bond strength. The head-to-head overlap creates the sigma connection. 4. WebThis type of bond is referred to as a σ (sigma) bond.
