Which of the following statements is incorrect for sigma and π -bonds formed between two carbon atoms?
(1) Sigma-bond is stronger than a π -bond
(2) Bond energies of sigma and π -bonds are of the order of 264 kJ/mol and 347 kJ/mol
(3) Free rotation of surrounding atoms about a sigma-bond is allowed but not in case of a π -bond
(4) Sigma-bond determines the direction between carbon atoms but a π -bond has no primary effect in this regard
