Question
Which of the following statements is not correct for sigma- and pi- bonds formed between two carbon atoms?
- 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.
- Free rotation of atoms about a sigma bond 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 this regard.
The correct answer is: Bond energies of sigma and pi-bonds are of the order of 264 kJ/mol and 347 kJ/mol.
