Given that the bond energy of C-O single bond is 360 kJ/mol, a C-O double bond is 750 to 800 kJ/mol and Si-O single bond is 450 kJ/mol, what is the bond energy of a Si-O double bond?

Question

Quizplus · Accepted Answer

The bond energy of a Si-O single bond is higher than that of a C-O single bond, but the increase in bond energy from single to double bond is not as significant for Si-O as it is for C-O due to differences in orbital overlap and bond character. Therefore, the Si-O double bond energy is significantly less than 900 kJ/mol.
