Hi everyone,
I have a question that how to judge the bond strength?Is it only consist with single bond,double bonds or triple bonds?

Triple bonds are stronger than double bonds which are stronger than single bonds.

When comparing the bond strength of two of the same types of bonds, for example two single bonds, the longer the bond length the weaker the bond. For example, H-Cl versus H-I. Because Cl is a smaller atom than I, the distance between the H and Cl will be shorter than the distance between the H and I. Since the H-I single bond is longer, it is weaker.
