Between CF,CO,CN and CC which bond have the highest bond energy and why?

Answer 1

In general, sigma (σ) bonds have higher bond energies than pi (π) bonds. Therefore, the bond with the highest bond energy among CF, CO, CN, and CC would be the CF bond. This is because the CF bond is a sigma bond between the carbon and fluorine atoms, which are both relatively electronegative elements. The strong electronegativity difference between carbon and fluorine results in a strong and stable bond with a high bond energy. On the other hand, the CO, CN, and CC bonds may contain pi bonds in addition to sigma bonds, which generally have lower bond energies compared to sigma bonds.
