← ScienceWhich mechanism explains why sigma bonds are stronger than pi bonds within a carbon-carbon double bond?
A)Greater electron density distribution
B)Increased ionic character of sigma bonds
C)Reduced steric hindrance within pi bonds
D)More effective orbital overlap in sigma bonds✓
💡 Explanation
When carbon atoms form sigma and pi bonds, stronger orbital overlap occurs in sigma bonds because they are formed by end-to-end overlap, leading to greater electron density between the nuclei. Therefore effective overlap explains observed strength difference, rather than density, ionicity, or steric effects which require different orbital orientations.
