Bond energy depends on the hybridization of the carbon atoms, which affects the bond length and strength:
- C(sp3)-C(sp3) (e.g., in ethane, single bond): Longer bond, lower bond energy (~348 kJ/mol).
- C(sp2)-C(sp2) (e.g., in ethene, double bond): Shorter bond, higher bond energy (~614 kJ/mol).
- C(sp)-C(sp) (e.g., in acetylene, triple bond): Shortest bond, highest bond energy (~839 kJ/mol).
Thus, the order of bond energies is:
C(sp3)-C(sp3) < C(sp2)-C(sp2) < C(sp)-C(sp), which corresponds to A. I < II < III.
C(sp3)-C(sp3) < C(sp2)-C(sp2) < C(sp)-C(sp), which corresponds to A. I < II < III.

The Order of Bond Energies
To understand the correct order of bond energies for the given carbon-carbon bonds, we must consider the hybridization and the nature of the bonds formed.
Types of Carbon Bonds
- C(sp3)-C(sp3): This bond is formed between two carbon atoms with sp3 hybridization, which means they are single bonds. Single bonds are generally the weakest among the types of carbon bonds.
- C(sp2)-C(sp2): This bond is a double bond between two sp2 hybridized carbon atoms. Double bonds are stronger than single bonds due to the presence of both sigma and pi bonds.
- C(sp)-C(sp): This bond represents a triple bond formed between two sp hybridized carbon atoms. Triple bonds, consisting of one sigma and two pi bonds, are the strongest among the three types of bonds discussed.
Bond Energy Comparison
- The bond energy increases with the number of bonds between the carbon atoms:
- Single Bond (C(sp3)-C(sp3)): Lowest bond energy.
- Double Bond (C(sp2)-C(sp2)): Intermediate bond energy.
- Triple Bond (C(sp)-C(sp)): Highest bond energy.
Conclusion
