The sigma bond is weaker than the pi bond.

(B) The statement that the sigma bond is weaker than the pi bond is incorrect. In reality,the sigma bond is stronger than the pi bond because of the greater extent of orbital overlap in a head-on collision compared to the lateral overlap in a pi bond. Furthermore,the bond energy values provided in option $C$ are also incorrect as the sigma bond energy is typically higher than the pi bond energy.

Which of the following statements is $NOT$ true regarding the sigma and pi bonds formed between two carbon atoms?

A
The sigma bond determines the direction of the bond between carbon atoms,but the pi bond has no primary effect on this.
B
The sigma bond is weaker than the pi bond.
C
The bond energies of the sigma bond and pi bond are $264 \ kJ/mol$ and $347 \ kJ/mol$ respectively.
D
Free rotation of atoms around a sigma bond is possible,but it is not possible in the case of a pi bond.
