Which of the statement is not correct for sigma- and pi-bonds formed between two carbons atoms?
- 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.
- 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.
Answer
(D) Bond energies of sigma- and pi-bonds are of the order of 264 KJ/mol and 347 KJ/mol, respectively.
