A C–C bond has an approximate bond energy of 80 kcal/mol, while a C=C has a bond energy of about 145 kcal/mol. We can calculate a more general bond energy by finding the average of the bond energies of a specific bond in different molecules to get the average bond energy.
Which carbon bond has highest energy?
clearly, strongest C−C bond is in C2H2 because of presence of a triple bond between two carbon atoms. And triple bond has massive bond energy.
Why does CC have highest bond energy?
With increase in the atomic number, bond length increases and the atomic number decreases. Hence, C−C bond has highest bond energy.
What is the bond enthalpy of CC?
The bond dissociation energy of CO (1072 kJ/mol) is the strongest chemical bond, stronger than the N2 triple bond (942 kJ/mol)4.
