WebFeb 13, 2024 · Bond energies. The E-E and E-O bond energies for carbon and silicon are given in Table 7.9. 3. The bond energy for a C-C bond is slightly greater than for a C-O bond, while the Si-O bond is significantly stronger than the Si-Si bond. This difference is reflected in the chemistry of silicon versus carbon compounds.
