Which one of following statements is not correct of sigma- and Pi− bonds formed between two carbon atoms?
Held on 30 Apr 2003 · Verified 9 Jul 2026.
Sigma-bond is stronger than a pibond
Bond energies of sigma-and pi-bonds are of the order of 264 kJ/mol and 347 kJ/mol, respectively
Free rotation of atoms about a sigmabond is allowed but not in case of a pi-bond
Sigma bond determines the direction between carbon atoms but a pi-bond has no primary effect in the regard
