Question
Which of the bonds of a carbon-carbon double bond has more effective orbital-orbital overlap?
Correct Answer
Option B is the correct answer.
Detailed Explanation
A sigma (σ) bond is formed by end-to-end overlap of orbitals, resulting in electron density concentrated along the internuclear axis, which is generally stronger and has more effective overlap than the lateral overlap of a pi (π) bond.
Hint
Sigma bonds are stronger than pi bonds because of direct, head-on overlap.
