Which one of the following statements is not correct for sigma and Pi bonds formed between two carbon atoms?
Free rotation of atoms about a sigma bond is allowed but not in case of Pi bond.
Sigma bond determines the direction between carbon atoms but a Pi bond has no primary effect in this regard.
Sigma bond is stronger than a Pi bond.
Bond energies of sigma and Pi bonds are of the order of 264 KJ / mol and 347 KJ/ mol, respectively.
