The incorrect statements among the following for sigma- and pi- bonds formed between two carbon atoms is:

1. Sigma-bond is stronger than a pi-bond
2. Bond energies of sigma- and pi-bonds are of the order of 264 KJ/mol and 347 KJ/mol, respectively
3. Free rotation of atoms about a sigma bond is allowed but not in the case of a pi-bond
4. Sigma-bond determines the direction between carbon atoms but a pi-bond has no primary effect in this regard
