Which of the following statements is not correct?

1. Double bond is shorter than a single bond
2. Sigma bond is weaker than a π (pi) bond
3. Double bond is stronger than a single bond
4. Covalent bond is stronger than hydrogen bond

Correct answer: Sigma bond is weaker than a π (pi) bond

Solution

A sigma bond is stronger than a π (pi) bond because it involves head-on overlap of orbitals, which is more effective than the lateral overlap in π bonds.
