Sigma -bond determines the direction between carbon atoms but a pi-bond has no primary in this regardB. Sigma -bond is stronger than a pi- bondC. Bond energies of sigma and pi-bond are of the order of `264 kj//"mol"` and `347 kJ//"mol"` ,respectivelyD. Free rotation of atoms about a sigme`-`bond is allowed but not in case of a pi`-`bond. |
