WebStrongest bonds and weakest bonds [ edit] According to BDE data, the strongest single bonds are Si−F bonds. The BDE for H 3 Si−F is 152 kcal/mol, almost 50% stronger than the H 3 C−F bond (110 kcal/mol). The BDE for F 3 Si−F is even larger, at 166 kcal/mol. WebMay 25, 2024 · Intermolecular forces are generally much weaker than covalent bonds. For example, it requires 927 kJ to overcome the intramolecular forces and break both O–H bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100°C.
