Bond Energy and Bond Lengths

    Is it true that the tripple bonds ahave higher energy than doubble bonds and doubble bonds have more energy than singlebonds?

    So if we were asked to arange the following bonds from highest energy to lowesst energy it would look like this: N---N (nitrogen- nitrogen tripple bond) C--O (carbon-oxygen double bond) and S-S (single bond)

    How do we tell the bond lengths of bonds? for example how would we compare the bond length of H-Cl to Si-Si?

    Explainations would be really appericiated. Thanks

    In general - yes. But that's only an approximation. It will allow you to compare bonds between identical atoms, but I would not dare to use this approach to compare energies of any bonds, between any atoms, as you may find some nasty surprises.
