Bond Energies of Sigma and Pi-Bonds
Introduction:
Sigma (σ) and pi (π) bonds are two types of covalent bonds that can be formed between two carbon atoms. These bonds play a crucial role in determining the structure and properties of various organic molecules. However, there are certain differences between sigma and pi bonds in terms of their strength, orientation, and bond energies.
Sigma Bond:
- Sigma bond is formed by the overlap of atomic orbitals along the internuclear axis.
- It allows free rotation of the atoms about the bond axis.
- It determines the direction between carbon atoms, giving rigidity to the molecule.
- Sigma bond is stronger than a pi bond.
Pi Bond:
- Pi bond is formed by the sideways overlap of p-orbitals or d-orbitals.
- It exists parallel to the internuclear axis.
- Pi bond restricts the rotation of the atoms about the bond axis.
- Pi bond has no primary effect on determining the direction between carbon atoms.
Bond Energies:
- Bond energy is the energy required to break a covalent bond.
- The bond energy of a sigma bond is generally higher than that of a pi bond.
- In the given options, it is mentioned that the bond energies of sigma and pi bonds are 264 kJ/mol and 347 kJ/mol, respectively.
- However, this statement is incorrect. The actual bond energies of sigma and pi bonds are approximately 347 kJ/mol and 264 kJ/mol, respectively.
Conclusion:
The statement mentioned in option C is not correct. The bond energies of sigma and pi bonds are approximately 347 kJ/mol and 264 kJ/mol, respectively. Sigma bonds are stronger than pi bonds.
