Question

Which order is correct in listing the bond lengths from shortest to longest?

A. single, double, triple

B. triple, double, single

C. single, triple, double,

D. double, triple, single

Answer 1

The triple bonds are the strongest and hence the shortest. Then comes double bonds which are of intermediate strength between the triple and single bonds. And finally the single bonds are weaker than the other two.

This way, Triple bonds are the shortest. Then comes double bonds. Finally, single bonds are the longest among the three.

The order of bond lengths is given as,

Triple bond < Double bond < Single bond
