Which of the following statement is not correct? (a) Sigma bond is weaker than a pi bond (b) Sigma bond is stronger than a pi bond (c) Double bond is stronger than a single bond (d) Double bond is shorter than a single bond
Answer: Sigma bond is weaker than a pi bond
Explanation
The incorrect statement is "sigma bond is weaker than a pi bond" because a sigma bond is stronger than a pi bond.
Sigma bond: Formed by direct head-on overlap of orbitals, resulting in a strong bond.
Pi bond: Formed by sideways overlap of p orbitals, resulting in a weaker bond compared to a sigma bond.
