Bond energies of sigma and $\pi$-bonds are of the order of $264 \ kJ/mol$ and $347 \ kJ/mol$

Vedclass · Answer

(B) sigma bond is stronger than a $\pi$-bond because the extent of overlap is greater in sigma bond formation. This statement is correct.$(B)$ The bond energy of a sigma bond is typically higher (approx. $347 \ kJ/mol$) than that of a $\pi$-bond (approx. $264 \ kJ/mol$). The statement in the option reverses these values,making it incorrect.$(C)$ Free rotation of atoms about a sigma bond is allowed due to cylindrical symmetry,whereas a $\pi$-bond restricts rotation. This statement is correct.$(D)$ A sigma bond determines the molecular geometry and direction between carbon atoms,while a $\pi$-bond does not. This statement is correct.

Which of the following statements is incorrect for sigma and $\pi$-bonds formed between two carbon atoms?
